1989 Chevy Celebrity 6 cyl Front Wheel Drive Automatic Station Wagon 193000 miles
I have changed my ECM and the car is running much better but still have a few problems. 1- The fuse gets very hot and sometimes blows. 2- The speedometer has gone crazy, I'm going at 25 mph and it registers 65 mph. It started working as soon as I changed the ECM 3- The transmission suddenly seams to shift radically from one gear to another every once in a while. WOW! I'm going to go CRAZY with all these issues. I just put it in today, July 3, and was told that I would have to run the car for a while until the ECM "learns" and receives new data from the sensors. I was also told that it could be the "map-sensor" so PLEASE HELP ME. What's going wrong. One other thing, the EMC is not connected to the diagnostic plug so I can not perform a scan, WOW! Please help me. Thanks
have the same problem?
