Hello there, this is my first post here and I’m writing because of problem with my boxster. Today in the morning I’ve started my 2002 boxster and noticed strange sounds from the engine/ rear side of the car It’s a metallic, grinding sound like a loose piece of metal or something like that Sound disappears when you press gas and comes back once you loose the pedal, I don’t know if it changes while engine is warm Also, check engine light shown up yesterday, when I connected my BT OBD2 there was no error code. I came with that to workshop also, and they said it’s a -
I have 2000 Porsche Boxster S that is misfiring on nearly every cylinder. It started with symptoms of a bad MAF; typical sluggish on take off, CEL light with the corresponding code. I would disconnect the wiring from the MAF and it would clear up. I cleaned the MAF and plenum and it ran perfectly for about a day. Ordered a new MAF. By before I had a chance to put the new one in I got a flashing CEL and a massive loss of power. Put in the new MAF. It cleared up some idle issues but the loss of power and flashing CEL is still there. The codes show random misfire and misfire on 2,3,4,5, and 6. I'

I'm new to Renntech and hopefully I follow the decorum correctly. If not I apologize. Anyway, I have a 2000 Boxster S. It has been sputtering on take off and gave codes that suggested the MAF was out. I disconnected the MAF wiring and it greatly improved the performance. I ordered a MAF and by the time it came in I believe my car went into Limp Mode. I installed the new MAF and cleaned the throttle body but it still acts like it is in limp mode. I also changed the spark plugs hoping this would help. The only code I'm getting off it now is P1118 and also the codes for missing on cylinde

Hi All My first post here so please bear with me but pretty desperate for help. Have 2004 Boxster S and its, in general, running a bit rough (feels fuel rich). It also will also, on occasion, not go. Pulling up at a busy intersection and car reduces to Idle. Then put the foot down and the car stays at idle. Normally an engine restart gets things going again (although not always and sometimes requires a few goes). Bought a computer reader and found error codes P0102: Factory Fault code 115 - Mass air flow sensor - below limit P2135: Accelerator Pedal

1999, 996, 117k miles Due to leaking I recently changed my coolant reservoir tank, which involved disconnecting and re connecting 2 fuel lines.. Upon restarting the car I had a rough idle and CEL. I purchased a $100b code reader, read a bunch of stuff online and decided to clean the MAF sensor, change the air filter, spark plugs, plug tubes and coils. upon today's startup I get an erratic/rough/low rpm idle, flashing CEL and the following codes: P0102 mass air flow circuit low P1319 misfire emission related P1318 misfire cylinder 6 -
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 -
I noticed the dealer price for a MAF is $500-$600 when the same part number in a Bosch box is ~$200. Is there something special about the one the dealers source? Is there some value add or is it simply demand driven to the age of these cars? Based on reading several posts, stick with the model you have in your car when purchasing a new one. Posting this info in case others need it: 99660612300 non-egas a.k.a cable throttle (Bosch Part # 0280217007) 99660612400 e-gas or M620 option C4's and others (Bosch Part #0280218009) 99660612500 or 99660612501 newer egas version from 2002 up but ma -
I have an oil change coming up and I plan on changing the air filter in my 1999 C2 at that time. Is it worth pulling the MAF and cleaning it while I'm there? Last time I checked it with the Durametric, the readings were in spec, so I don't think it's that dirty. I am just unsure whether periodically cleaning it will extend the MAF's life by reducing the likelihood of build up, or if it will reduce its life due to applying chemical cleaners. Thank you! -
1999 Porsche Boxster 986 shows check engine light (CEL). Code read at autozone as P0112 Error Code (Intake Air Temperature Circuit Low Input). According to <http://repairpal.com/obd-ii-code-p0112>, the error code causes could be Defective Intake Air Temperature Sensor (IAT) Dirty air filter Defective Mass Air Flow Sensor (MAF) Faulty or corroded Intake Air Temperature wiring or connection MAF: Bosch 996 606 123 00 (serial number?:0 260 217 007) DME: Bosch 996.618.601.04 (serial number?:0 261 204 605). Lots of other numbers on DME. Can post image if required. After doing some researc -
Hi, Today I tackled my first DIY service on a 2006 c2. After the service the engine check light turned on, any help would be great!!! Here is exactly what I did: - I wanted to check the spark plugs so removed 2 coils and 2 sp, I put them back on as they were clean. I plugged the coils back on, screwed them back on. - changed oil and filter. - change air filter, cleaned the Maf carefully with Maf cleaner without touching any component - cleaned the inside of the throttle body as it was somewhat dirty. Dried it completely before putting it back on and changed the seal. Note that when I cleane -
I have a 996 3.4l (1999) tiptronic with 140'000km. The engine was rebuild at 80'000km and the tiptronic rebuild at 100'000km. I face a strange problem since many month. I try to explain symptom in chronological order. - When it rain during the night, I need to start two time the car. The car start alway from the first power on, but no power at all. I need just to power off and re power on and the car work fine. - One month after, the car is running on 4-5 cylinder after the second power on... lot of missfire. - The garagist change all 6 spark, 6 coil, the AOS (leak problem), the MAF and the t

The MAF in my 2001 996 turbo died. I called the dealer in Oregon from whom I buy my parts and they wanted $570, and told me this was down from MSRP of about $770. I bought the Bosch unit from Amazon.com for $149.95 with free shipping. It is an exact replacement; it even has the Porsche part number on it. I just wanted to pass this on because it was such a good deal. -
I'm tring to find out what MAF (Mass Air Flowsensor) was used for this car: http://www.supercars.../cars/1627.html See picture of the Yellow one. The previous owner scrapped the old MAF and nobody know what should be installed. (Not even at Gemballa, They do not hold these records anymore). Is there anyone out there with a simmiliar car and willing to check the partnumber for me??? Location of this NAF, see: -
My 2002 turbo tiptronic occasionally almost stalls when coming to a stop while it's warming up. It dips down to 500rpm or so, maybe even less, but it then bounces back up and keeps running. It stalled on me completely a couple times, but that stopped once i replaced the air filter. I've tried cleaning the MAF, and I *think* that it helps, but i can't convince myself that the MAF is the problem because it's rather intermittent. I tried capturing some durametric logs, here's the relevant part: RPM THR KPH MAF V AFR 801 4.3 16 1.5 0.92 0.89 778 4.3 15 1.46 0.93 0.9 732 4

I am having a few issues with my 2001 turbo. The problem is undoubtedly the previous owner, but besides that, I have some other issues. The car is throwing a PSM/ABS light after driving for anywhere over like 15 minutes or so. When I got the car it had a BMC filter, so I suspected the MAF may be the issue from the oil on the filter or just dirt. So I pulled the BMC and replaced it with porsche paper ( the car now consistently pulls 1.0+ bar ) and then pulled the MAF and cleaned it thoroughly. After cleaning the MAF, I drove it and the difference was unreal, perfectly smooth shifting, no m

I need some advice. I have a 1999 996 with a 2001 engine. I need to replace my MAF, but not sure how to tell if I have and e-gas or not. Does anyone know how to make the distinction? Thanks in advance!!
