ok my gf just bought herself without taking it to a mechanic but it is a 1995 contour se V6, it was ok for first few days and now the tach bounces around and like loses power and dies and doesnt wanna start back up but does turn over. one day went to autozone for the computer test, they said it was a pfp or a pip sensor? a egr vavle was closed, and o2 was reading lean, went today after wiggling and looking over and was gonna get this pfp or order but decided to get another test and now was some other sensor they couldnt even find out what it was and the MAF, so i got the MAF and still messing up any1 know anything about this please no sarcaism, i need help on this

 

found the problem, the wiring coating is all broke off by the plugs on almost every plug and included the crank sensor (which happens to be the pip-profile ignition pickup). the wire for the crank sensor was bare and twisted around so i taped up the wires and runs alright again, anyone know where i can get the whole wire harness for unde rthe hood?
