Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

When it was then running, even though it was at warm running temp, the car would idle higher like it does on a cold start, around 900rpm and could feel the extra pull when holding the brake when in D.

If i turn the car off with the key, it will then crank as normal and start but still run the idle as if it is cold.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi all, New to the forum and still new to 996 ownership but had a problem come up yesterday. I've got a 2003 996.2 tiptronic with 90k miles. The problem came about that when the engine was fully up to temperature, when I came to a stop at a set of lights the engine just cut out. No roughness to any indication, it was just as if I turned the ignition off. When i tried restarting the car, it wouldn't fire up as normal, as 1-2 seconds of cranking, but needed to crank for maybe 7-10 seconds and then slowly started to run. By this, it wasn't the usual immediate fire up but cranking then would gradually start to fire and then run. When it was then running, even though it was at warm running temp, the car would idle higher like it does on a cold start, around 900rpm and could feel the extra pull when holding the brake when in D. If i turn the car off with the key, it will then crank as normal and start but still run the idle as if it is cold. It happened three times after this on the same with the same issue of high revs and long cranking after it cut out. No issues with power delivery but didn't push the revs too hard. After getting home, left the car for a couple of hours and went back out. no issues starting from cold, the engine had the cold idle revs then settled down as normal, but after maybe 25 minutes of running, it cut out again, and same issue of long cranking and high cold start idle. No smell of fuel or any warning lights on the dash, but haven't had any codes read to see if anything is pending to report. Going to get it booked into a garage to look at but wondering if anyone has had anything similar with theirs to help point to where the issue may be coming from. Thanks, Joseph

Fuel pump is my guess.

A similar thing happened to my 2004. It ended up being the valve lift cover solenoids - not sure if that was a feature on your model year, but sounds exactly like what happened to me (search my posts on this forum) - so perhaps could be that. good luck!
