1. The car needs two trys to start.
2. Once running, high rpm, then settle down idling. Sometimes it will idle down 'till engine is dead.
3. Try the car forward or reverse(if still running), it stalls.
A code scanner always point to the MAP sensor as being out of range. I have a Chilton Repair Manual for my (FORD) Grand Marquis 1990. A check of the old and new MAP sensors give me an output well within the required range.
Now where can I have the PCM re-progammed/re-flashed?
Or can I purchase a new one and provide them with the calibration code, VIN#, Mileage, etc?
have the same problem?
