The first time the engine stuttered on my 2002 7.3 was this morning on the highway. I eased off of the pedal (my cruise is broken) as I started down a grade. The engine stuttered and then acted as if nothing happened.

The second time it happened was when I was working the throttle and clutch to start from a stop in first gear. It stuttered, I let off, it resumed operation, and I went at it again successfully.

I installed a DP Tuner 6 position chip about 3 weeks ago, and was in the 80 Econo setting at the time. A recent scan has shown that my clutch switch is defective, which is why my cruise control doesn't work.

Hope you're carrying a spare CPS and wrench, just in case! /ubbthreads/images/graemlins/grin.gif

When does the under valve cover harness clip thing usually begin to rear its ugly head?

[/ QUOTE ] I am peripherally aware of this issue. What is it, and what are its symptoms?

Thanks, Ryan!

What a great resource.

It looks like it's fairly easy to check for this problem, and not quite so easy to get to it.

I believe that I performed a buzz test last week with the engine running. While it was doing the self test, it ran the idle up, and back down, and did some things with the injectors that made it run a little rough.

Would this problem, along with my newly-discovered rear main seal leak, be covered by my 5/100k engine warranty? With all of my fuel system mods, to say nothing of the intake and chip?

You're both welcome for the link. /ubbthreads/images/graemlins/warmsmile.gif

The warranty thing depends all on which dealer you go to. Dealer may not care that you've got all the mods, and just do the service... but I doubt it...

And yes, I still keep one and an 11mm wrench in the glovebox.

I hope you mean 10 mm! /ubbthreads/images/graemlins/smile.gif
