I had that happen to me once or twice but only for a moment and then it cleared itself up. I've always attributed it to a spot of bad gas or something...though I always use name brand gas (shell, texaco...yadda yadda.)

 

i think you should check your air inlet housing, maybe you have esomething loose, those stock boxes are junk. and even aftermarket intakes, rattle apart because of the torque that the ralliart puts out, make sure all of the air parts are secure

 

holy shmokes!!!! look at all this input!! There is so much that it " could " be. Just hope that its nothing to serious for you

 

ok dumb question what is "wot"

 

wide open throttle

 

-UPDATE-

I seem to have fixed my problem!!!? It's been two weeks now, and no stuttering. Not exactly sure which of this worked, but here is what I did.

I took apart my intake and re-installed it, making sure everything was nice and tight, including the MAF sensor. Unhooked piggyback, and re-connected, making sure all connections had good contact. Re-set ECU. Ditched my Denso spark plugs, and installed NGK's.

I've punched it (WOT) in hot weather, cold, and when the car had been running a few minutes, and a few hours. The problem has seemed to disappear?!

I'm kinda suspecting something was up with the plugs, but time will tell. Thanks for everyone's input!
