  1. Please please check out my previous post that explains more of the problems and multiple attempts by dealer to fix them. They are frustrated too I'm sure
  2. Hi. Thank you for you reply. Thats the problem NOTHING of this issue has ever thrown a code. That's the ongoing frustration that the dealership keep saying that every one of the parts that replaced should've each to Thrown or shown a code. Especially with the extent that the problems were showing themselves.
  3. 2007 Carerra S 114,000 miles I have had a roller coaster ride of dealership attempts to find and repair a hunting idle, hesitation at low-mid RPM range and now a interrmittant intense fuel smell emmitted from right front fender area. If you refer to my previous Tech question you will see multiple parts have been replace trying to find this problem. Throttle body, MAF sensor, Crankshaft sensor, Oil seperator and now the car is back in again for all the same problems. They now have done a fuel system 'smoke' test and did not find any leaks. The mechanic now thinks the Charcoal Fuel Canister feels too 'heavy'? and thinks it might be over saturated with fuel and not purging properly? He thinks this might be causing an OVERLY rich gas mixture 'possibly' contributing to the idle, running and performance issues AND at its extreme moments of further gas fumes induced into the canister it is then purging out to the atmosphere. Does this all make sense? I guess the fuel smell from this over saturated canister is possible.... but what about the performance, idle hunting, hesitation... etc issues? I should also note that the problems are usually intensified more when the engine is hot. The dealer has had the car on/off about more than I this past month. Any help is GREATLY appreciated! thank you!
  4. Anybody out there have any experience with decent warranty companies that would write a high mileage 2007 911 113,000 milesI'm coming off a great extended warranty from Vehicle One, but unfortunately they don't write Porsche over 100k. I know some companies out there do.. and it might be pricey...and it might not be their top tier level of coverage, but i'm interested in it.Any suggestions? and / or who to stay away from ??I know fidelity has some good reviews. Has anyone heard of Endurance?
  5. All the ignition coils and plugs had been changed approx 20k miles ago. They don't think its a vacuum leak as its somewhat intermittant and it hasn't thrown any codes.. Although i'm pretty tired of hearing the 'code' excuse as this issue has NEVER thrown any codes... meanwhile they have changed all those supposed bad items. Thanks Ahsai for your suggestions... i'll run that past them when i drop the car off again on Monday
  6. 2007 Carerra S Firsly, my apologies for the long account of events, but my car has been in/out of dealer about 6x in 2 months. They can't figure this out.. so i'm hoping someone out there can shed some light on this.. thank you! I have had an ongoing and increasing problem(s) for about last 6 months. Not sure if these issues are related or coincidental, but here goes.... Started out with the car dieing out upon its first startup every morning. It would always start up perfectly the 2nd attempt and then a little rough but then even out and be great after that. Dealership said to run a can a seafoam through the gas every other fill up. This would slight help reduce the problem to intermittant but not complete improvement. Then I noticed the idle becoming a little bit rough at times and gas mileage reducing from about 16 mpg to about 11mpg without any change in driving habits. I also would occasional notice it difficult to smoothly start moving off from a stop because of a slight engine hesitation and found myself giving it more gas that usual to start off the 'line'. (Never felt like a clutch slipping issue). Also cruising between about 3000-4000 rpm I could feel a slight infrequent 'hesitation' in the acceleration. Then I started to develop (what dealer calls) a 'hunting' idle when stopped with engine running. I also noticed a drop oil pressue to near minimal to what looked like zero at times on the gauge. Then one day the a/c starting blowing warm air along with significant drop in Oil pressure. Dealer replaced the Oil pump. The 'hunting' idle continued whereas I would be sitting still with engine running and see the rpm fluctuate from about 750rpm and rise up to 1200 and drop to as low as 300. The odd part is this would happen at EXACTLY 20 second intervals. If i gave it some gas.. it would stop for a few moments then start again. (NOTE.. I NEVER HAD ANY CODES or ENGINE LIGHTS). Dealership replaced the Mass Air Flow sensor ( MAF) .. of which did not help and 2 days later not only did it still hunt.. but actually died out sometimes while idling. I took it back in and dealership said it was the Crankshaft sensor causing the hunting and carbon buildup causing the initial startup problem. They did a engine decarbination and replaced the Crankshaft Sensor. I received the car back again and STILL had the hunting problem along with the 'hesitation' feel with low speed cruising. Seemed to be worse when engine was hot. Then one day during the crazy hunting / hesitation issue i pulled into my garage and opened the drivers door and smelled an intense FUEL smell which was coming from the right front fender area. Took it back to the dealer who swears that there is nothing wrong with the fuel system or vapor canister, etc. (note.. the fuel smell only happened 2 or 3 times and dealer could not reproduce it). HOWEVER, this time they noticed when they gently rested their foot on the gas pedal the RPM when into a crazy constant hunting mode from 750rpm (up to about 2000 down to about 400). Again a ECU code still has NEVER came up. Dealer disassembled the Throttle body and cleaned it up, then reistalled. Still had the hunting problem and hard 1st start issue. So they ordered and installed a NEW throttle body. Still no change int the problem. So he put the new Throttle body back on and (oddly enough) discovered it was nearly impossible to remove the oil cap while the engine was running. So he determined it was the Oil Seperator that was bad. NOTE: It never had smoke emmiting from tailpipe or any CODE thrown. So.. they replaced the Oil Seperator which appeared to stop the hunting problem, rough idle and hard start problem. HOWEVER, THEY NEVER FOUND THE REASON FOR THE FUEL SMELL? I picked up the car 2 days ago.. This is the current status of things... The hard initial start is much better.. so far has started up on first attempts... and Resting idle is pinned at about 750rpm and doesn't move. However, I still feel a slight intermittant hesitation when slowly accelerating or trying to maintain about 3-4k rpm. AND... at idle.. if i rest my foot gently on the gas pedal.. (for example.. trying hold about 1,000rpm, I still get hunting significant hunting oscillating the rpm from 750 up to about 1200 and down to about 500) The service manage said this is normal because the car thinks i'm moving and i'm not?? huh?? If i try doing this when engine is cold or warm (just after intial warmup) it doesn't do it... but will do it badly when hot. NOTE this is the Arizona heat! Service manager feels this is normal and stated it was hunting much higher before with light pedal touch, but says this is normal. Can you PLEASE let me know your thoughts on this? I do not think a light touch of the gas pedal should cause a crazy oscillation of the RPM's. Also the car still feels like its hesitating during slow, smooth acceleration. Like its trying to take a breath while its increasing speed? Does it sound like a fuel issue? They stated fuel pressure was good, but they still do not know the cause of the fuel vapor leak/smell from before? The gas mileage is still at around 12 mpg (with standard driving) The one thing the service manager also cant understand is why the ECU still hasn't thrown any codes during any of this? Could the ECU be bad? Can a worn clutch cause any of these symptoms? (its never during shifting) Why the gas smell/bad gas mileage, etc? Please... any suggestion would be greatly appreciated!! THANK YOU!!!
  7. Have u figured out the correct part number to the thicker wheel in u'r photo? I also have both the sport wheel and a xpa wheel and it definitely does not look as thick as the image in u'r pic. Does anyone know the part number of this thicker one? Loren: Thanks for the reply. The wheel I'm interested in is listed as an option by Porsche (XPA, I think) and is designated "Thicker Steering Wheel". Attached is a picture showing the difference between "Sport" and "Thicker". Ed Loren: Thanks for the reply. The wheel I'm interested in is listed as an option by Porsche (XPA, I think) and is designated "Thicker Steering Wheel".
