cant always trust your ford dealers either. my brother has a 99 Gt and his alternator went. so we braught it to the ford dealer and they tell us it wasnt the alternator it was the cpu. so they replace the cpu. 2 weeks later the car dies again, so this time we replace the alternator ourselves. another 2 weeks goes by and the car dies again. turns out the cpu they gave us was defective and it totally messed up my bros car. all the wiring in the car had to be replaced, another computer installed, and just about every sensor had to be replaced. Then the best part of it all was the ford dealer refused to pay for the damage their computer casued. cost my borther $3900 to fix.
poor bastard.
