High RPM Stutter

Hey all,

I've got a 2002 Black SVT with 82k mi. The car runs well at lower revs, but loses power and stutters above roughly 4200 RPMs. Sometimes if I let off the throttle and get back on it, it'll run great all the way through. Other times the problem persists. I also just moved from CO to PA and had the car shipped, but I don't see how the altitude would cause this issue.

I'm suspecting either problems with the MAF, IMRC, or something in the fuel system. Anybody have any insight or experience?

Thanks.

I'd start by cleaning the MAF then seeing what that does.

Look the coil over for any signs of cracking (including the base, so it needs removal).

High rpm/load misfire is often seen as the first sign of one that's failing.

Thanks. As soon as I got home from work last night it started to pour. I picked up some MAF cleaner. I'll post with updates soon.

Keep us posted, start with those two options then if those don't work run down the rest of the list.
