Intermittent Problem
Hi Everyone,
I have a 99' Powerstroke, and am having a problem where about every 60 or 70 miles (est.), the check engine light comes on and the engine goes into a "limp mode" of barely running. I stop the truck, kill and restart it, and then it does fine for another 60 or 70 miles. I changed the fuel filter a couple of months ago before and put several hundred miles on it before this problem appeared.
Thank You

May be as simple as an Under valve cover harnes has come loose
When its running poorly ,,unplug the wiring to the valve covers one side at a time ,,one side won't make a difference in the way it runs ,,that is the bad side..
Look for this...

Yes, like Barry said. Pull codes. That's what the SES light is for. Doesn't sound like a typical CPS problem. Usually they shut down the engine as if you turn the key off. However, stranger things do happen.

I had changed out the cps last year, and then again with the new version at the cps recall sometime ago. Carry the old new one as a spare.
Can I pick up a code reader that is reasonably priced, or is this a dealer thing?
Thanks again for all the info.

Like Chris said, don't really sound like a CPS issue, but those new gray ones have been making for some weird problems. You could swap out your new one for the old and see if that helps. Post your location and there may be someone near with a reader.
