Low rpm problem after starting hot 964 turbo engine..
Guys,
unfortunately my car has a strange problem that happened 5 times already.
When I start a hot engine, it starts without a problem, but has very low revs and almost dies, the AFR is 20.00, and this only happens when the engine is hot.
If I press the gas and exceed 1000 rpm everything works normally, when I take my foot off the gas its about to go off.
This morning I started the engine normally and drove to a meeting for 30 minutes. After an hour I came back and what I described above happened. Despite the low rpm and the engine not running smoothly, I drove further. After 10 minutes of driving, everything returned to normal, the AFR at idle speed was again 15.5-16.0. I went to a meeting and after 10 minutes I came back, got into the car, started the engine and everything was fine.
Does anyone have an idea what could be the cause?
Thanks
K
