Is there a code that determines if the ECM is 100% working ? My 5.7EFI Throttle body has an alarm the my go on sometime and then a reduced speed will follow. This does not happen all the time.So far all systems were checked or replaced and I thought it was fixed. It ran great for 3 outings then the last time it did what it was doing for the past year. I would run for awhile then the alarm would sound and the engine would slowdown. I would say limp home mode (guardian mode) but I'm not sure now what the problem is. What is the life of a computer ECM?
