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.

Mine did the same thing as yours. Engine stuttered at speed, mostly around 60-75 mph. A few times when I would shift, but mostly at cruising speed. Just like I cut of the key and then back on real fast. I thought CPS, and maybe it is/was?? That was about a year ago and it has not happen since.

I just read the above and I am sure to be dead on the side of the road now. I am just pushing the CPS to its limits /ubbthreads/images/graemlins/biggrin.gif

I guess it is covered under the 5 year 100K. If so how do you prove it if it comes and goes? No code, just stutter. Or just DIY and forget the $100 warranty and dealer hassle??
