Example complaints

1991: “As the weather is getting warmer the engine revs and drops uncontrollably. The car also stalls at any speed. I have had it even stall on the highway. I hear this is a common problem on this particular type of ECM unit, please check into this for me. If I hadn't taken a defensive driving course I could be dead right now.”
NHTSA complaint #747780, filed 2001-071990: “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.”
