I'm having driveability issues- 03, V6, auto, 125k miles. Once in awhile she loses power, CEL comes on, dies. Starts right up 5 minutes later. EVERYTHING under the hood has been replaced. MAF, Crank Position Sensor, plugs, wires, coil pack, all O2 sensors, MAF again. Cyl 3,5 misfires & O2 sensor codes. My dealer whom has absorbed a large part of the cost (used car, VIP customers) believes it's the ECM. Your thoughts? Possible faulty ECM? If I buy one from Ebay, does it need programming (fobs will)? Side note- when locking/unlocking car, only driver's side lights flash.
TIA!
