I sent my 1993 XJ-6 Sovereign w/a 4.0 six (Vin#SAJHW1745PC666992) TO A Jag dealer in Seattle for a new head gasket recently and they nearly totalled the car. They wrecked the ECU (among other things) and the company in Florida I sent it to for repair stole it and sent back one they said was the right one. It isn't or at least is not programmed correctly. Runs OK w/the MAF disconnected but not with it connected. Anyone know how to program one the right way? Thank you.
