Hello, I have a 1995 Mack ch613. The truck doesn't get used a lot but it happened twice in two hours of running yesterday. What happens is the electronic malfunction light goes on. The throttle then increases to full, the throttle pedal has no effect then, the only way to get the truck to throttle down is by engaging the clutch which will drop it back to idle but when you release the clutch the throttle returns full. You have to shut the truck off to get the electronic malfunction light to go off and to fix the throttle increase issue. Has anyone had this issue? Thanks Jason
