Which is the best cps today? Just installed grey cps from ford, trucks stumbles and set code. bad cps? 2003 7.3 f250 200k.
When it stumbles the cel comes on. Truck continues to run good, 70mph not an issue.
Seems like I need to be light on the throttle though.
Had the same issues before installing new cps. code p0344.
The International dealer gave me the dark blue one and it has not given me any trouble in two years. (The parts store one I found in the truck was though.)
Not to derail the thread, but I've got a question for you guys. I ordered the RiffRaff CPS (dark grey/purple o-ring) as a spare. My truck has no codes or anything, but the idle quality isn't the best, and there is a very slight shake to the truck while idling. Would the riffraff CPS fix this? Or am I better off not messing with it? My gut tells me "If it ain't broke don't fix it", but at the same time, I'm curious if the new CPS would make a difference.
Slight shake - I'd start with addressing anything that could help reduce air in the fuel system. Hutch mod, fuel lines from tank to bowl, FRx or equivalent, that sort of thing. Has any of that been done on your rig?
When I was researching which one to get "everyone" said get the grey one but nobody said dark or light and I got the light. My engine runs fine, no clue what's in it, now I'm curious to see if there's a noticeable change....assuming what's in it isn't the same as what I bought.

I would try it and see. If there's no change just leave it in and keep the old one as an emergency spare. My new one's been living in the glovebox, and I ordered one for my friend to keep in his as well since it's a small cheap part that can save the day.
No fuel mods as of now, was pretty set on doing the frx a while ago, but having to grind down the baby's butt to make sure the fitting didn't rub made me a little nervous. But as loud as the truck is at idle, I'm still tempted to buy it.
