Hello,
My name is Martim and I'm new to dorkiphus. I just bought some wheels from a member who reminded about the website and now here I am. I have a 99 996 C2 and I am being attacked with problems at the moment, this is quite a list and I would sincerely appreciate any help/advice you guys can give me, here we go: Stalling - This has been happening for a few months... I'll be driving on the highway at about 60 or so and if I push in the clutch and leave it there the engine shuts off and the power steering goes too. This happens every time I keep the clutch in at highway speeds. As soon as I let off the clutch and press the gas again the engine comes back to life and so does the the rest of the car. Anyone heard of this problem? Spark plugs maybe? Airbag light - This just happened today; I washed my car and after doing so I got in and the airbag light wouldn't go off. I disconnected the battery but it is still on. I read that this is not an uncommon problem with 1999 cars and that it has something to do with the seat-belt buckle or some kind of wiring harness under the seat. Any suggestions? Filling the tank - Every time I go to fill up the tank, I put the nozzle in and start fueling, after a few seconds the pump shuts it off as if the tank were full (when it is not). I then have to spend a great deal of time standing there and very very slowly pumping the gas (so slowly that I cant even put the nozzle on the first latch and leave it). I was looking at some diagrams of the fuel system and it looks like there is a valve right where you put the nozzle in, maybe this valve isn't relieving enough pressure? The "more" part is not as immediate but I would still very much appreciate any help or suggestions. The driver side mirror cover on the visor is broken (it just falls off when you pull the visor down and the lights don't come on). Is there any way to buy a new mirror cover or do I have to replace the whole thing? Also, my keyless entry stopped working a few months back and neither of my keys unlock the car when pressed, I took it to the dealership and they said it would cost about 600 dollars because they needed to replace the keys and the module in the car. Any other suggestions? Thanks for any help. |

Martin,
How many miles are on your car, do you have the records for it? Do you know when the last major service was performed? The easiest question to answer is the gas tank. 911s are notorious for needing to be filled slowly, that doesn't really sound all that abnormal. For the airbag light, I'd pull the code, you need to use an OBD-II scanner and find out what it's telling you about the airbag system. It's entirely possible it's something or nothing, and let's face it, airbags can be nice and if there's a problem addressing it would be a safety issue. There are several reasons I can think of to cause the stalling issue, again, if you could provide some more information on the car's service history that could really help. Does this happen every time you do this, randomly, when cold, when hot? If you rev it at idle will it stall as the revs drop? |

Both of my 964s have slow-fill issues so I think it's a characteristic of the breed. I find that if I drape the filler hose over the side-view mirror, I can pull the trigger to the first click and leave it there. I don't mind standing by the car to fill it, though, because about 50% of the time someone usually stops by to ask questions about the car.
The stalling issue is clearly your worst problem. Do all the idiot lights on the dash come on when the car stalls? My first inclination would be to look for an electrical short of some kind... I agree with Andrew that you should take your car to the dealer or find someone with a scanner for the airbag issue. Don't mess with that. There was a thread posted to the 964 forum on Rennlist recently where a guy was driving down the road and his airbag spontaneously deployed. Everything else sound like Porsche quirks that you can fix by looking your car up on PellicanParts.com and buying a few replacements. This is standard fare...

I think you need a SRS scanner which may or may not be included in some OBD-II scanners. I have an airbag light on in the M3 which is still on because my contacts with OBD-II scanner/reset tools did not have the SRS functionality.

Slow filling is "normal" for Porsches. I usually only put the nozzle half in and that seems to allow full flow. Air Bag , what they said, probably nothing but you don't want to take a chance of malfunction.
Don't know why you are pushing the clutch in whilst driving/coasting, should only be in for the length of time it takes to change to a lower or higher gear. If that is what you are doing , then I would suggest a "tune up" plugs, air filter etc" Dirk

Martim,
Welcome to the Board. The airbag light is a know issue for early 996/Boxsters. There is a grounding issue with those early seatbelt buckles. You need a redesigned buckle and grounding kit(s) for ~$85 per side. Renntech.com has detailed DIY description. http://www.renntech.org/forums/index...&hl=airbag+tsb

My educated guesses:
1) Stalling You'll always loose power steering when the motor stops. When you let the clutch back out, the car is esentially being 'push started' and will come back to life. Both are 'normal' behaviors. The original stall is not. The 99 is pre-egas throttle bodies. Therefore it has to have some sort of idle control valve (ICV/IAC/etc). Wondering if thats getting gummed up and not reacting fast enough to keep the car running. Common problem on old cars. Try pushing in the clutch SLOWLY (let the revs come down very slow) and see if it stalls. Another cause can be a dirty throttle body/bypass screw putting too much of a burden on the IAC. 2) Airbag light No clue. Get a code reader and/or search the boards. Ive had good results w/ our durametric. Good long term diagnostic tool to have. No relation, just a happy customer. http://www.durametric.com/ 3) Filling the tank Common IMO. Seems many european cars have this sort of problem (must be the filler neck shape or something). The pumps fill nozzle detects splashback to shutoff. Pull the nozzle 1/3 - 1/2 way out and fill. That somehow cleans up the turbulence at the nozzle end and stops premature shutoff (theres a funny joke in there somewhere).

Martin,
welcome aboard... Do you have any aftermarket upgrades? The Cold air intakes from K&N, EVOMS, etc are known to enhance the stalling issue that you described. The ICV off the 1999 cable throttle is the real likely culprit. It can be cleaned/replaced efficiently. Airbag light is well documented and is covered by the belt buckle TSB. Filling the tank: search on Renntech I think this one is well covered there with a fix. My 99 996 fills up fast and all the way. knock on wood so it is not the norm. Let us know.

welcome martin, sorry about your troubles. w/o a code reader it will be pretty difficult to determine exactly what's causing your problems as for the fillup, while they are finicky, yours sounds like it's on the extreme end of the spectrum. have you tried putting in the nozzle 'upside down'? (w/ the trigger side facing TOWARDS the car as opposed to the traditional way?) |

If you want that OBD code read, I think your local Autozone store will read the code for you for free.
