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.

I did take the MAF out and it looked brand new/super clean but I have no records of it being changed so might b worth a punt on a new one anyway

When I bought my 3.4 it had a very shiny and new (but totally unbranded) MAF fitted so I swapped it for a proper Bosch one and it did run better at low RPM's.

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.

8 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hey all, I wonder if anyone can shed any light on this issue I seem to be having. I have a 1998 996 cabriolet 3.4l tiptronic. It is a bit of a project car to get fixed up, it has been off the road for a few years and I have it back driving now. One think I have noticed is that evey so often it seems to stall when I have stopped and shift from drive to reverse (highly annoying while trying to park on busy roads ) it seems to happen when the car is warm. Has anyone experienced this before and have any ideas on what to try?? I have cleaned the icv and the MAF sensors but the issue still seems to be there. I was thinking it could be low transmission fluid and needs a top up? As it also seems to hunt revs a bit when driving at say 30mph with the engine under low load Any thoughts appreciated Cheers Loz

POST 2Original post

Stalling when warm could be the crank position sensor. My 3.4 (manual) did this and a new sensor fixed it.

POST 3Original post

could also be the MAF - i had this on my car and Porsche fitted a new MAF - all OK afterwards

POST 4 / ORIGINAL POSTEROriginal post

Cheers guys, I will look into the crank sensor. I did take the MAF out and it looked brand new/super clean but I have no records of it being changed so might b worth a punt on a new one anyway

POST 5Original post

You can buy really cheap MAF's off ebay now for about £15 but the issues they can cause have been well documented. When I bought my 3.4 it had a very shiny and new (but totally unbranded) MAF fitted so I swapped it for a proper Bosch one and it did run better at low RPM's.

POST 6Original post

Worth cleaning the throttle butterfly too. you have to douse the ICV in carb cleaner, you should be able to hear it clicking if you shake it about otherwise it will still jam.

POST 7Original post

Does it start straight away when it stalls, if not it could be the variocam solenoid or actuator, this is a big Job so hopefully it's not that

POST 8 / ORIGINAL POSTEROriginal post

Yeah I shift it I to park and it starts no issues
