Hunting Idle
Hello all,
I have researched this extensively but am still coming up short on an answer so here is my issue:
2000 Boxster 2.7
80000 Miles
Tiptronic
The idle is going up and down from about 600-800 when in Park. If i am just at idle speed with the car in Drive the idle is a little rough but nowhere near the bouncing up and down.
It doesn't happen when the car is cold and first fires but as the idle settles in, it starts the issue.
There is NO Check Engine Light
Air conditioner on or off doesn't change it much at all.
I can pull the oil cap off easily and the car idles terribly when i do, so no vacuum leak in the crankcase and AOS is probably OK?
The MAF was replaced to try and solve the problem a year ago and it seemed to be better but has since gone back to the issue. ( I don't drive the car much)
I added a bottle of fuel injector cleaner today to see if that helps.
The care seems to run fine when moving. This seems to be strictly an idle issue.
I'm prepared to clean the throttle body, clean the new MAF, check the AOS, check the O2 sensors (somehow), replace fuel filter if need be etc. but would appreciate a point in the right direction.
Bill
