Hi all,
91 325ic, yesterday I went ahead and replaced the old Autolite's the previous owner had in there and put some fresh NGK ZGR5A per forum recommendation.As soon as I started the car, I noticed it started idling faster (around 2200 RPM), engine was cold, but it is too high anyway.
Once it warmed up, it decreased to ~1400, it also seems to take longer to decelerate when shifting gears.
I guess this engine didn't like NGK's so I'll get a new set of the Autolite copper it had before and put those in.
Anybody have an idea why this would happen....
