1993 Isuzu Stylus problems

Filed Jan 11, 2001 · Acceleration, Electrical · FL

The symptoms of this fault are most notably erratic idle, idle revving and dropping, idle dipping often with engine dying, idle hanging high above 2,000 RPM, and engine dying or stalling for no reason with no trouble codes. These symptoms will often only occur in warmer weather as the metal circuits of the circuit board seem most vulnerable to short circuits at solder cracks when the temperature within the car is above 80 degrees fahrenheit. In temperate climates, the symptoms may first show themselves as soon as the weather warms and plague the owner all summer long, only to subside in the fall with the cooler weather and then reappear the next spring. Certainly the faulty ecu/computer symptoms of unintended vehicle acceleration and vehicles leaving drivers stranded, sometimes in traffic, pose an equally serious hazard to the health and well being of the driver of the vehicle with the AC delco ecu/computer and those around that vehicle.
