I have a '97 4.2Q. Has anyone else noticed the somewhat abnormal throttle response of these cars? When blipping the throttle in park or N it seems as if the engine keeps revving for a brief moment after the pedal is released (giving the impression of very slow response). Does anyone know what causes this? It seems like an ECU problem.

It is not areal "positive" feeling. I have the same feeling. What is your transmission code?
I switched to 00011 within a week of purchase. This helped as it "disables" the learning mode of the Tran. control module.

i switched to 00011 as well. doesnt seem to help throttle response. dont see why it would either. nobody else has noticed this?

Could it be because it is an electronic throttle and not a mechanical one?

I forget the details on your model year, but electronic throttles do have a "disconnected" feel. If you are used to cable throttles and quick return, this can be a downer.
