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’ve checked Rennlist, Pelican Parts & Clark’s Garage and there seems to be a variety of answers, but not as high as his 2500 rpm:

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.

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

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Went to Lakeside yesterday, to watch. Met a mature gentlemen in driving an Alvin open wheeler. Found out he also had a 1988 944S, exactly the same as mine. He asked if I knew about a fix for a high idle when WARM . He said it was 2500rpm! When cold it started normally and idled at correct rpm. I suggested places on line he could check to get an answer. He said he was not on-line and not into “technology”. So I volunteered to find a answer and call him back. He gave me his landline number. I’ve checked Rennlist, Pelican Parts & Clark’s Garage and there seems to be a variety of answers, but not as high as his 2500 rpm: vacuum leak ICV sticking TPS Has anyone had similar issues? Is there some testing that needs to be done to isolate the issue? Any assistance would be much appreciated.

My a/c 911 does it. Been told it's probably vacuum leak somewhere. Should sort that out one day 🙄
