  1. Hoping to purchase this car.. They ran a DME and this shows only 19 Over Revs in Range 1 with none across the other ranges.. there are a "high"? number of misfires? Is this a concern or perhaps normal and maybe just require plugs / coil packs? My 1st Porsche.. I hope...
  2. Hi all, This will be my first post, thanks for a great forum ! I've recently purchased a exhaust system from Design911 in the UK which has the valvetronic function on. This is said to replicate the PSE which my car does not have factory installed. Wired it up and put the vacuum hoses, tested the system and it works fine. Over to the issue for my car: When starting up the car, the neutral positon of the valves is open, which means a lot of noice from the exhaust. When switching this by the solenoid, sending vacuum into the system and the valves closes. This means less soun
  3. Unfortunately, I am back with another problem or problems........ A couple of days ago a check engine light popped up on my 997.2s and because it is my daily driver, I was not able to immediately diagnose the issue. I went ahead and ordered a "Carsoft POR II" scanner off amazon as i thought it would help my understanding in what the problem was. (Getting to the point.....) Today while I was driving home from class, the car was running very rough. I decided to pull over and give the scanner a go...

  4. I am having an intermittent misfire issue with my 996. It started a few months ago, when the battery ran down after not driving it for a few weeks, and I had to jump the car to get it going. After a few miles, I got a CEL and the car started to misfire. Upon arriving at my location, which was just a short distance away, I turned off the engine and went about my business. Upon returning to the car, it ran fine. No CEL and did 65mph all the way home, which was about 20 miles away. All was good, until a couple of weeks ago, when on a slow drive, I got a misfire and the CEL came back on.
  5. Hi The alternator brushes disintegrated at 105k miles, so I bought another whole alternator unit from eBay, fitted no problem checked the voltage at the battery it was above 14v. The battery was then flat the following morning so I bought another battery Bosch S4 figured the alternator cooked a cell before throwing the towel in. Since these changes the check engine light is coming on and the car idles roughly when I comes off the choke or returning to idle from revving, in fact it drops lower than normal idle speed before reluctantly returning to 750, also getting rotten egg smells from e
  6. 2007 997 was running rough. The Durametric said misfire cylinder one. Checked the forums and saw most likely culprit was either bad spark plug, bad ignition coil, or both. Oreilly’s had the Bosch spark plug and a coul that was labeled Import Direct. For the sake of convenience I bought the plug and coil from them. The coil was actually the newer version Beru (oem) with the longer bolts. Much easier job than I ever imagined. There are good tutorials on YouTube. Engine runs great and I cleared the codes. No check engine light and codes haven’t returned.
  7. Hi guys, I'm new to the site so please be patient with me? (Also grammar isn't my strong point) So, I've owned my 2003 996 carrera for the past 2 years and for the most part its been trouble free. I got it with 110,000 miles its now got 130,000. Maybe 5-6 times over the last year it's started misfiring as I come to a stop, it starts up after maybe 2 minutes and misfires for 30-40seconds, then runs fine. The last two times this has happened the display has said low oil pressure as it's been misfiring, but then starts running normally with no mess
  8. If I run the car at less than 1/4 tank full it's very smooth great acceleration and responsiveness. With engine running I went and filled up with 99 octane as usual and straightaway the engine stutter comes back!!!!!!!! Fyi it is NOT fuel quality. I've started a new thread for this but it's an old problem mentioned in previous posts and unresolved. Basically the ctt 06 with 114,000km has been hesitating and stuttering for a while when accelerating particularly under boost in lower gears through the rev range of 2k 3k 4k ish rpm, it also will vibrate and stutter revving the same rpm
  9. Hi All, So today, after putting gas (Shell, premium) in my 2014 Cayenne base, I got on the freeway and shortly after, the check engine light came on and Cayenne started shaking abnormally. I was able to turn around and get back home but I noticed 1. When I stop, the CEL flashes and the Cayenne shakes a lot more 2. When I press on the gas, it takes a long time to pick up speed (really struggling). I connected the Durametric when I got home and I see the following misfire fault codes on it. Anyone have any suggestions? Cayenne has around 62k miles on it.
  10. 2002 911 C2 Coupe I'm having the classic misfire on cylinder 1 when the car is wet. I used contact cleaner on the ignition wire plug into the coil and it works fine for now. I/m sure when it gets rained on it will misfire again. Already replaced spark plugs. I discovered there is a tear in the little orange gasket (green arrow in photo) on the ignition wire connector and water is getting in there when it rains. Anybody know where I can find a replacement without buying a new $812 engine wiring harness? Thanks Tom
  11. Trying to track down an issue I'm having on my 2013 TT. It has a stumble when accelerating in the 1800-2500 rpm range in basically any gear. If I punch it, it will sometimes act like a misfire. I've changed plugs and coils and looked for vacuum leaks in the front and rear of the engine but didn't find anything. I hooked up an Edge CTS to it and watched various parameters over the past few days but don't see anything obvious. Spark timing looks good and consistent, fuel pressure looks OK, Long term and short term fuel trims look OK (see below), and O2 sensors don't appear to be mal
  12. H! I have an 996 - 99mod manual 3,4L. When i start up it seems like it misfires. It`s kind of a knocking sound. Sometimes it stops on idle. When i push the throttle for a ouple of seconds, it smokes a lot and then the knocking goes away. After that, I let it Idle - but it slowly rises from 800rpm to around 2000rpm, then it drops to 800rpm again and do the same thing over and over again, Does anybody have a clue? This is the fault codes i found: P1601 -CAN timeout - instrument cluster P0600 - CAN timeout Tiptronic
  13. I've continued to snag and fix pretty much all the issues on my ctt, im left with a stutter at 2k 3k & 4k rpm. Seems to get better the longer I drive ie after 500km was smoother but then I disconnected the battery and was back to a very lumpy low rpm up to 4k then it flies. I decided to pull out my dip stick whilist running expecting a dip in rpm and some lumpy idle but nothing happens. The idle is fine and stable at 500rpm, I know a lot of people with vac pvc leaks have bad idle but not me. So the question is should the pcv system be affected by sip stick out or do I have a leak I d
  14. Hi everyone, I've been reading the RT Forums for a while but now I'm finally registered in order to try and track down an issue I've been having. I've searched for related issues through the forums already, but nothing is showing up which is a match for mine. '99 2.5, 5 Speed, 99K Miles Only upgrades are headers and catback. I've owned the car since March of this year and it's been great so far. I've even taken it to the local PCA Autocross. A couple of weeks ago I was cruising on the freeway when my CEL came on steady, no blink. There was no noise or indication to me that an
  15. I had the following error codes registered and a very erratic tickover when idle, I had both Variocam actuators replaced, 3 months ago, and I have again got the same error codes as I had before the actuators were fitted: P0300 - misfire detection P0306 - misfire cylinder 6 P1371 - valve lift control checksum error P1360 - valve lift control cylinder 6 The misfire is very sporadic, it does not have any regularity to it, it can happen when the car is first started, or when the car is warm, and when the misfire occurs the car can be driven and at the end of the journey (sometimes) the misfire
  16. Finally got my CTT back after a head gasket job, new & rebuilt turbo and timing chain. Stealership went into receivership before work was done but fortunately they allowed mech to finish assembly. Mech informed me all went well but cyl 7 misfire is coming in. Swapped plugs and coils to different cyl to troubleshoot. Still came in as cyl 7 misfire. I see from a quick search this problem could be a simple connection or fuse issue. Unfortunately I'm at work for 5 more days and can't fix CTT for wife. If someone could fast track me to the potential fuse I can try to guide my wife through the h
  17. Hi all! Many months ago I had a problem with the MAF shutting down the engine/staffing it on startup (tried cleaning it no luck). I disconnected the MAF and it ran fine on the default values, just burning more fuel. Now its time to get my emissions test so I bit the bullet and bought a new Bosch MAF. I installed the MAF, and the durametric software cleared the fault codes and the new MAF is giving off normal values hovering around 10-13 on car idle. The issue I am having is that I am receiving multiple misfires on all the cylinders through the Durametric software when the new MAF i
  18. So here's my problem. I've got a 2001 Boxster S with the factory 3.2L engine and ~70,000 miles. I bought the car in 2010 with 38,000 miles on it. I have it serviced regularly every 5,000 miles at the independent dealership, iAutohaus, where I bought it. They specialize in European luxury cars and I trust them as much as a person can trust a dealership, I guess. My wife drove out Monday from Phoenix to Albuquerque with no issues. After spending the night at a friend's house, she left to drive on to her final destination in Santa Fe. After leaving her friend's house, she called me saying
  19. Hello All, I purchased a 2005 Carrera base with 60k a few months ago. Being a Porsche fan all my life, this was finally my first one. The car fax and records looked good but since I got it, its has been nothing but problems. Within the first month, the water pump went out. Considering the car is 7+ years old, I was okay with that. The following month the CEL came on with misfiring sum and all cylinders. I took it to TPWS in Austin and they said I needed to replace the spark plugs and coils so I had them do it. Now 2 weeks later, the CEL is on again with misfiring sum and misfiring 3, 5 and 6
  20. My 2000 Boxster S w/105k (body) 40k (engine) is acting up. Last fall, I got caught in downpour and inches of standing water, getting splashed hard by other cars. The CEL started flashing and the car was nearly impossible to drive past 3rd gear (no power and bucking) until I could get off freeway to let it dry out. It had several misfire codes set. Ever since then, it's been a little less smooth than I had been accustomed to, and now it is misfiring and bucking below about 2600 RPM all gears, all temps, but ONLY with high throttle opening (e-gas). Tipping the throttle in seems to be fine. H
  21. Long time lurker, first time poster. I can usually find everything I need here by searching, but I'm stumped by this problem I'm having... Car is a 2000 C2 with 91k miles, and has run strong with the normal maintenance for the three years that I have owned it. I should also note that in the last year I have replaced plugs, coil packs, MAF sensor, and cleaned the throttle body. Not sure if this is related to my problem, but I was blowing leaves from my driveway last week and also blew them from of the spoiler fins of the car. Anyway, the next morning the car started, but the engine was runn
  22. When the check engine light came on, my mechanic plugged the car into his laptop and got a misfire reading. Since the car was not due for a plug change, he attributed the misfire to bad gas and drained the tank. That didn’t fix the misfire light from coming on and he accordingly changed the plugs. After changing the plugs the misfire reading still appeared which led to changing out the coil packs. That didn’t fix the problem either, so he borrowed an ECU from another TT and put it in my car…NADA. We’re currently scratching our heads wondering what is causing the problem. Anyone else experience
