CPS issues (recall...)???

[CSIPSD]

It could be completely unrelated and a bent push rod, but last week I picked up my truck from the shop after getting the rear end fixed... They did the CPS recall without my ok. I was pissed but o well...

Now this week I have a obivious miss, #8 fails a cont test and is at 4.5-4.7% value on AE...

What issues are people having with the new CPS's???

I love my new grey CPS. The truck has never ran so well. I can finally run the windshield wipers without the engine coughing and I don't feel I need to drive in the slow lane to be able to pull the dead engined truck over and restart.

I even bought a spare grey CPS for the glove box.

I've heard that the new grey cps's have been causing issues with the #8 cylinder on some trucks. I have a grey one and haven't had any problems yet knock on wood.

I just had a new grey cps recall performed also and a #8 cyl. contribution fault as well of 4.6 %. The truck seems to run fine but I'm still curious why also? I was also wondering what does the AE stand for? Thanks!

Auto Enginuity, an OBD 2 scan tool.

The #8 misfire is a well known issue with the gray CPS. If i wear you I would go back and demand you get your black CPS back.

I'm debating picking up a spare cps myself. According to carfax, my new to me 99.5 hasn't had the recall performed yet. So since it's apparent I shouldn't get the grey one, where should I get a black one? I've heard of a blue one, is this true?

same issues on multiple trucks (and mine) with the new cps. I have all new push rods as well and still fail number 8. Depending on the tune, I can fail number 1 and 3 as well.

I hate the new cps.
