Hello, I got this 85' 318i that now has too FAST an Idle. 2500-3000 RPMS, a high, steady idle. It just started doing it last week.
It starts fine, idles OK, but once the car warms up the idle jumps way up!
I checked the linkage, & it has no intake leaks . . . . . just a high, steady idle.
I tried changing the Air Stabilizer off another BMW I have sitting around and still the same. Exactly! Now after I messed with it awhile, it seems it's high no matter what!
The Air Conditioner is turned off
Anyhow, does anyone have any ideas? I seen a post on idles that surge, but nothing on if its a high, steady idle.
Any ideas would be appreciated!!
