Just got it back ... They replaced the coil pack. It's idling normal now ! But let's see in a few hours once it's stone cold. He didn't mention anything about dirty valve or vac issues though
Ah. Didn't realize that was called also coil pack. I'm used to the individual coils used in a 6 cylinder. Thanks.
30 degrees out and the car sat for 4 hrs and started perfect and now it idles perfect and feels much better
Maybe I need to replace mine? I have a high idle when warm. But I know the intake is filthy and have bad vacuum hoses. As soon as it's warm I'm going to work on it.
I’m with you on that! It’s really cold up here and a big snow storm coming tonight. But doing some research on the E36 build and electrical, a lot of people have or had idle issues whether being low and rough like myself or really high. What I researched it comes down to the coil pack or injector(s) in really cold temps they start to leak into the cylinder after the car sits for a bit thus giving that rough start in cold and a couple of high revs burns off that excess fuel. But I’m no mechanic I’m also thinking about changing my own oil…… What do you think the dealership will charge ?
