“The first ecu failure occurred under warranty and caused the car to barely run. It was replaced by john kraft chevrolet (they no longer sell Isuzu's). During the past 3 yrs/30000 mi I have experienced all of the following: erratic idle, idle revving and dropping (most common), idle hanging high above 2000 RPM, and last but certainly not least, idle dropping with car often stalling. This happens when the clutch is depressed for a stop. The car seems to pick busy intersections to stall. There is a problem with the AC delco ecu used in this car. …”
