Idle jumping up and down
Posted: Sun Mar 13, 2022 4:55 pm
Hi
My E12 1981 has a m30B28 engine. I have an issue which seems hard to solve. Car runs great but when I stop and car goes to idle the rev is going up and down. Sometimes even stalls. After 3 ,4 times the idle goes steady to 950 rpm
I’ve checked all I can think of. Valve clearance, throttle body adjustment, ignition timing, new plugs and ignition wire TTS and cold start valve works as it should
Anybody has an idea what to look for?
