Suggestion

Might be an idea to check the metering block pin hasn’t become stiff in operation, this can cause poor idling or stalling.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Hiya, I recently bought a Porsche 944 and amongst other issues, I found that after running it at idle it would start to idle very low (300-500 rpm) and eventually cut out. I would really appreciate some suggestions as to why it does this and how to fix it. I'm sure I'll be back asking for more advice soon. Thanks a lot, Max Edited by Max Lavey on Monday 14th August 17:47

POST 3Original post

I had a similar problem with my 944S2 which would also cut out and was difficult to start when the engine was warmed up. Seems to be a common problem with the 944, where the DME (fuel pump) relay goes faulty. It’s an easy and cheap fix to change this yourself.

POST 4Original post

Ive seen this before. It was a problem with the fuel pressure damper located at the end of the fuel rail, the rubber diaphragm perishes.

POST 5Original post

+1 ras62; pull the vacuum line off of the fuel rail damper/regulators- if there is fuel present that is wrong. Ethanol fuel seems to rip through the older parts lately - had two fail on a 944 turbo recently

POST 6Original post

Might be an idea to check the metering block pin hasn’t become stiff in operation, this can cause poor idling or stalling. Be careful when you remove the block because if its working properly the pin might pop out, it’s very finely machined and should be treated carefully.

POST 7Original post

Metering head only on 924; KJet. OP said 944 - DEE or DME depending on model year, but both had ECU controlled sequential injection instead of KJet.

This is a source reference. Confirm exact model applicability in the original material.
