if your running the grey ford recall cps you will fail the #3 and #8 cylinders almost every time.
so swap in either the delphy hts 101 cps, bwd cps with its occasional wiper issue, or the international cps.
i had the wiper issue with the bwd cps, so i am awaiting the delphi hts 101 cps, my truck idles and has a miss like you are describing with the grey ford recall cps

@drive one- the harness looked pretty good( when i say pretty i mean i took a quick look and once i reconnected #3 connector i double checked all connections that are under valve cover, nothing to the obvious was present). but if it was a chaffed/bad wire or connection wouldnt it trigger the check engine light? or shouldnt it so to say?
@blue 99-im not to familiar with the wiper issue..??.. but where can you pick up the better cps?

the recall for CPS sensor is black sensor= replace grey sensor= do not replace

we just replaced my dads uvch on his 2000.
his service engine soon light was on from a glow plug wire being bad. so if you were having harness issues you would have a code. and ses light.

the light grey cps is most likely the ford recall cps that is junk!

type in delphi hts 101 on amazon thats the cps you want. or you can get them at advanced auto.

it will be a grey/or black cps, but you will notice the head on it is much larger.

the recall cps almost always fails the #3 and #8 cylinder contribution test.

FWIW everybody wants the old black ford cps sensors because the trucks run great with them besides the random dying issue that can happen with any cps made.

So I assume by cps you mean crank sensor, is what it sounds like you guys are talking about which is actually CKP but I digress haha, this might sound dumb but check every thing like alternator output, cyl. blow-by (pinch off your ccv and take your oil fill cap off and see if it puffs smoke with the firing of each cyl or use a special gauge), leak down test and compression test and anything having to do with oil or fuel pressures. But we've had lots of trucks with alternator issues run exactly like it would with a bad CKP, including my own truck). If you have an IDS or other full function scan tool monitor your ICP and IPR, and check the wiring harness to each of those. We had a issue with 7.3 ICP connectors filling with oil and causing problems, also with the IPR harness pigtail insulation melting and arcing together.

first and foremost... the cps has always been the universal initials for camshaft position sensor, alt out put is 12.5-13.5 volts.
