Idle speed when oil cap removed...
Ive read on a previous post that the engine should start idling unevenly whenever the oil cap is removed.
The reason I ask is that yesterday while checking the oil level on '88 coupe, I didnt notice any particular difference with the cap or off...it seemed to idle exactly the same !
I'm fairly new to Porsche ownership, so can someone please tell me what should really happen when I remove the oil cap as I am concerned that I may some problem.
