A Slight Miss
I think I feel a miss while cursing, which is usually under 2k rpm.
I do have a light tap when the engine is cold but it goes away as it warms up. it kinda feels like a bump in the road when it happens, but it doesn't happen in the same spots on my road, I have no check engine light and 135k on the car just changed plugs wires and power packs and just put on a cold air intake.
Any help would be appreciated, let me know if y'all need more info

But seriously folks, I had a similar issue with my '03 GT that first popped up around 95k miles--at light loads and lower RPMs there was a stumble.
It was the EGR valve sticking. Being a cheap SOB I just disabled the EGR in the tune and the stumble went away...

I'm from new jersey...its inevitable
aside from my horrid spelling, a slight stumble would exactally explain it, I don't feel it when accelerating or idle, it just feels like it falls on its face for just a second then goes back to CRUISING just fine.
I'll look into the EGR valve...but it sounds like a task
Love yours too, but it looks darker than mine. I love dark blues.

When I looked the part up so I would know what I was looking for I was like wait a sec there's 2 newer parts that look like that on the other side of the engine, but the EGR valve looks like its original. I also read on another forum that if the valve was bad it would throw a code, and I have no code?

okay, I'll spray it down today before I go to work and tomorrow I'll take it off and inspect.

Also as the PCM will not actually know the cause it would likely only throw the misfire codes--I don't think the freeze-frame data would show anything either.
