'86 944T - Runs at idle speed only when cold?
I've got a 1986 944 turbo. I love it, and it's in great
shape, however, it's picked up a problem I'm not familiar
with. In the morning, I start it and it seems to run great.
I back out OK and turn down the downhill driveway and
everything seems OK, but as I accelerate out on the road,
the engine RPMs suddenly drop to idle speed, as though I'd
pulled my foot off the gas, or the electrical system had
killed the spark, but the engine doesn't die, it doesn't
even seem like it will die, it just drops back to idle
speed. It did this twice as a hiccup, like someone quickly
cut the engine spark, then turned it on, but this morning it
was serious. If I gave it gas, the RPMs would rise to
perhaps 2200 max, then drop back to idle, then try to rise
again, then drop back. It did this 20- 30 times or more.
Nothing I did would give me higher RPMs, then suddenly, I
felt it begin to fire at higher RPMs and it's working
perfectly again.
As soon as it warms up and runs correctly, it runs fine from
then on. I've seen this now a total of 3 times in two
weeks, once in the morning and once leaving work - just as a
single or perhaps double hiccup, then this morning's serious
event.
Any suggestions on what this is?
