Is the ECM adding to much timing at idle?
I set base timing at 4-6* advanced. Reconnected the EST wire and the ECM added 20* or more on top of that. That can't be right can it, at only ~1000RPM's
Would it do this if it detected a lot of extra fuel?
Or it probably would do this if the TPS sensor was reading to high. Right?
