Bucking
I had all the same symtoms you discribed. Changed bad plug wire ( taylor) and no results, then cam sensor, No change , checked crank sensor ok. then on my way to work I was just saying how overall this is a good car and as soon as I said that she responded by bogging down. I turned the key started again and limped home. noticed the tach going wild. I said cant be brand new cam sensor. i remember reading in a few posts about a bad DIS mod. I just changed it out a year ago, but it was a standard brand. I had a old back up from pick a part but it was a Motorcraft. after installing it fired right up, took it out for a spin and leaned hard on it no problem. Took it up to 15 psi. no prob in 3 gears. So Im saying all this time it was a poorly made aftermarket POS module. Whatever you do whether its buy new or get used , get a motorcraft of ford original parts. They last.
