Hi Everyone,
I have an 88 formula 5.0 5 speed. It was bucking like crazy and would stall at an idle. I gave it a tune up and nothing. I noticed that after a while the ecm quit on me. The check engine light would no longer come on and the car would not start. I replaced the ecm and the car lit right up. It lit the check engine light. I checked the code and it was a code 42. I replaced the spark timing module and the car immediately ran great. No stalling sputtering or anything. I took the car for a ride and was very pleased at the way it ran. When I came back I shut the car off and went inside. I went out to start the car and again the check engine light would not come on. This ecm is dead now too. The fuse is ok. Any ideas???
