1990 Cadillac Deville V8 Front Wheel Drive Automatic 162000 miles
This car was running great on Monday and went to start it on Tuesday Morning and it ran real rough. No power to even get up a slight hill and rough idle.
Took it to auto repair and had them run a diagno on the car and they told me that the ECM was bad and that it was not sending power to several of the injectors and basically running on half the cylinders.
Went and bought New ECM and replaced, took prom card out of old unit and put in new unit. Cleared all the ECM and BCM codes from the system and started car, still have the same problem car runs like a junker no power.
Call the shop that diagonoised the problem and was told that the ECM had to be reset by someone with a scanner this is the only way. So after a very expensive part replacement still have to fix, car has new wires, spark plug, distributor cap, a rotor button. Any advance that might fix this problem would be greatly appreciated. I believe the Manual say that the EMC can be reset thru other mean, I do no believe the the first Ecm was bad, could the Prom card be the problem? I don't want to keep spending money on this car by guessing, and taking advise from a shop that I don't think they know what they are talking about.
