Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Constant stalling and/or high revving of engine. Stalling usually occurs when comming out of gear and idle goes down to 500rpms or lower and stalls out. After some research I have found the problem to be an acknowledged ecu problem that should be replaced and Isuzu never did.”
NHTSA complaint #10030614, filed 2003-08“Engine idle jumps above 3000 RPM after pulling to a stop. Will occasionally return to normal after several minutes. Car races and accelerates uncontrollably with clutch engaged until idle speed returns to normal. Iac and sticky throttle cable have been ruled out. Problem appears to be related to the delco ecu, as experienced by many owners of vehicles with 1.6 and 1.8 liter fi 4xe1 and 4xf1 engines. Manufacturer has refused to acknowledge this problem.”
