Hello, since I have to fight for a long time with high idle speeds (never under 1000 rpm) to very high (1600 and then sinks down to 1200), I have come up with a test to show if the engine pulls false air, the removal of the oil refill cap is with the running engine. I did that, but only briefly because I was injected with oil (is that normal?) and see, engine has run exactly immediately (on something over 1000 rpm). First I did it only with the oil meter and since nothing happened here, I tried it with the lid. Is that now a concrete indication that it pulls false air and if yes, where do I best start with the search? ^^ Thank you in advance PS: Yes, I already started a similar thread. However, I mainly talked about white smoke from the exhaust, which got done after a Kat change. For less confusion about this here a new thread:P
