Hello All,

I need your help with this.

I have a '98 Z24 - 2.4 with the Auto trans. The car runs very well except when cruising at about 1500-1700 RPM's. It feels like it is chugging along almost as if you are in too high of a gear if it was a manual trans. I replaced the plugs, wire boots, coils, coil housing, cleaned the TB and put in fuel injector cleaner. No codes are coming up.

The car idles and runs very strong other wise. I need to get this fixed though. Any thoughts where I can begin to look? I figured the ECM - little computer looking module where the coil housing is attached might be faulty.

Thank you!
Dan

Is there a website for buying OEM Delco items? I am sure the dealer is going to rake me over the coals.
