The CPS seems to be one of the usual suspects in a whole raft of ills, of the 7.3 powerstroke. Its almost able to be classified with the GEM module of the 99 to 01, powerstrokes, for weird things going on, with these engines.
Ford's recall CPS, that was light gray, has been more than a pain. Its caused more problems, than it cured. Only thing good about it, that I can really tell, it doesn't just die, and leave you on the side of the road. But, if your engine doesn't run, or run well, you are going to take another means of transportation. I guess that is called solving the problem.
Out of the three gray ones that I own. I have found one, that actually passes the contrib. test. I was amazed, so, I am running it, compared to an old black one that I have. So far, its a little quieter, a little smoother, and fuel milage hasn't been hurt. I guess I will see how far it takes me.
