i pulled out the CPS today i got from my local chrysler dealer 3 days ago,it tested bad!!,what the H is goin on ???,i did not test it before install,guess i should have?looked around and found one i had replaced a year or so ago,it tested ok,put it in went for a drive,everything ok!!,i also looked over the wiring at the back on the drivers side,some of the injector wires had some cracking in them,so i applied some liquid tape (ever hear of that?)i also changed the ecm back to a used one i had,im getting really gun shy about getting more than a block away from the shop!!!
