Is my ECM Bad???
I have a Sentra 2001 with 95,000 on it. It was having some trouble starting every once in a while...and when I was at high speeds (i.e. 80 mph) the RPMs would go down to 0 for a split second and bounce back up. This didn't happen every time. Check engine light never came on. I took it to the dealership who told me I need a tuneup. Then then called back later and said it needed a new ECM. I went to pick it up and the car was totally inoperable. Dealer said that the ECM was not giving any readings the computer so they weren't able to get any codes, which means it's bad. Dealer told me I would need to tow it off the lot. I drove it for a month with only the RPM problem. So, I don't trust them much. Now I don't know what to do. Do I fork over the cash for the new ECM, or tow it home and try the tune up. Any suggestions?
