Default ecm questions.

Just checked online to see availability of a ECM. Rock Auto has none in stock but O'Reilly's (sp?) does. I used 1993 Mustang, 5.0 since I don't know the year or what car you are talking about.

Remember, after a ECM or battery is disconnected the ECM has to relearn everything. Years ago a dealer tech told me to start the car and hold the rpm's at 2500 rpm for two minutes then idle for one minute and then two minutes at 2500 rpm then let it idle before shut off (all this while parked).

Also, was the ECM "reflashed" after you had it open?
