Thread: stuttering?

Over the past few weeks I noticed my 2004 gtp has seemingly randomly felt like it has be stuttering. I have noticed it at all driving speeds, even just idling if I remember correctly. My friend noticed it today when I picked him up this morning it was happening when we were coasting at like 45mph and then it stopped, but about 15-20 miles later we were on the high way doing 70 mph and it started again. The RPM's are not quivering, and it almost feels like my wheels are not balanced (but it would happen all the time if that were the case correct?). The whole car rocks a bit, and its even visible in my hands on the steering wheel. As far as mods I only have a CAI so far, Let me know if you need more info in the description I'll do my best.

the steering wheel shaking sounds like a wheel bearing going bad. but stopped at idle you wouldnt feel that...

Hmmm yea It seems to have gotten worst so when it first started it was mild and I didn't pay attention to it. So for some reason I feel like
I remember it happening while idling. I bought my car over the summer with 34000 miles so I'm going to assume it has original spark plugs
And such so I think I'm gonna get then checked out to see how they look, and see if I can get a hold of someone with a scanner to check with misfires
Because I'm not entirely sure what that would feel like. And if I was mistaken and it stops once the car stops moving then ill look into a bearing issue,
But again it doesn't happen all the time.

Just an update. I finally got a chance to stop my car once it started happening and I'm certain it
Has something to do with my front driver side tire region. Meaning either the barring ... Or
Something to do with my brakes catching or something. Because in october it was squeaking
But my mechanic said the pads were fine(he changed them anyways) and said they were
pulsating and a couple of months Later it started again. So hopefully progress will
Be made soon.
