Just in case this may help someone else: My car (2000, 996, cab with 165,000 miles) quit cold on 3 separate occasions recently. First on interstate at 60 mph; second in stop/go traffic; third while idling in a parking lot. On each occasion, attempts to re-start were useless. Starter turned, motor cranked over, but no firing. After each wrecker ordeal, it always started just fine several hours later. I was clueless. I even had the (original) fuel pump and associated relays replaced on spec. I had to find the cause as I had to be able to trust my car to get to work at al
I was driving a new to me 04 S in the mountains of Tennessee last weekend. With about a 1/4 tank (maybe a little less but the warning had not come on) going up or down a hill (I can't remember) on the interstate, the engine sputtered and quit as if running out of gas. No check engine light. Pulled to the side, waited. It started. Went 10 miles, same thing. Got to an exit. Got gas. No more problems. Other facts. I recently installed two new fuel pumps. Also, I cannot fill the tank at a gas station at the normal rate without the pump quitting -- as it there is a vent that won't let air be di
I have had a good run with my 986 and no problems for a good while, but nothing lasts forever... In the last month the car will randomly stall and refuse to start back up for an undefined period of time. When it happens all the lights on the dash will flash on as if the key has just been turned to the on position. The starter will crank the engine happily but there is no ignition happening. This will last for an unknown amount of time (20 min or a day) and then the car will start right up again. Only to stall out later at some unknown point. (15 min or 1 hour). I have hooked the durametr
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
