Which CPS is the good one?

Tonight on the way home the truck cut-out a couple of times and the check engine light came one. When I got home I read the codes and it said something about a faulty CPS. I have a spare gray one...is this a good or bad one?

The original black one, is better than the grey one, but was the one that tended to die and was recalled. I stilll have one installed in the truck and a spare (no it's not for sale ). I had a grey one in the replacement engine, and when I changed back to the original, I gained about 2 MPG.

Here's a thread that should tell you what you need to know.

Thanks klhansen...I spent about a hour reading through the thread...very interesting. I'll check to see which one is installed now and go from there. It sounds like a crap shot since the Black ones are no longer available though. Do you recommend I not install the Gray one and go with the newer Blue one?

I decided not to install my spare gray one. I have a gray one installed now. I ordered a couple of the blue ones from Riffraff. Hopefully they'll be fine.

When I put a blue one in place of the grey one the dealer forced on me, it felt like I had chipped the truck. I finally rounded up enough black ones that I am running those now. I couldn't feel a difference between the black and the blue, but going to the grey makes it feel like you're running on 6 cylinders.

Thanks RT...interesting there is so much difference between the different CPS's.
