Yesterday while doing some reading I saw a guy who tested 15+ CPS models. He said the best results (other than factory black CPS) were a CPS from Borg Warner.

I looked it up. It costs $25 and can be had from o'reilly's. Today I picked one up and swapped it for my CPS.
Once I verified that mine was a grey started the swap. I wasnt going to touch it if it was black.

The BW CPS was noticeably larger than the grey OEM one. So much so that I wasnt sure it would fit! But it fit perfectly.

Got the BW in and it was an IMMEDIATE difference. The idle is much smoother now. Before it was inconsistent, about 100-200 variation in idle speed. Not much, just enough to be noticeable. That seems to be all gone now. This new CPS only went in today, so I will be on the look out for changes in the truck, but so far I am pleased! The grey is in the glove box along with a 10mm ratchet just in case.

I will report back in a few days with more results.

I got 2 BW CPS's from an online parts store that had them listed as same part as the black CPS (International P/N). Even in the picture they were black. I got them in and they were grey:matt-roloff: I felt the magnetic strength of the sensor and it wasn't even half as strong as the black CPS. I could pick up one end of a wrench with the black CPS. I still have them in the glove box as spares. Everyone is out of new black CPS's, RiffRaff has some used black CPS's for $10 shipped.

What is the part # of the BW CPS

Can't beat that price

Sorry, it was a Wells CPS I found thinking it was the equivalant of the black CPS.
