I will second the lack of confidence in autozone.Stuck in Tacoma with a bad CV axle.Took them three tries before they finally gave me my money back to start over.I had been replacing those axles on my river rats for a lot of years.I got stuck with a die in the wool dyke that didn't even know the software she was using at the counter let alone what I was really looking for.The whole conversation started with my car did not have one of those and she was willing to argue with me.I was holding the core in my hand.Funny stuff now.

I know with ford there are ways to read trouble codes using the trouble lights on the dash.Jumper the diag mollex and watch the trouble lights blink.count the blinks and apply to trouble code chart.Pain in the ars to say the least but a life saver maybe in the back 40.

Any luck?
