anyone?

spark plugs or a bad coil pack will be my guess.

Is it when you first step on the gas or any time you try to accelerate quickly?

[stdriver]

anytime im just driving around, constant speed. then also sometimes when i accelerate.

just changed the maf so im going to try it now. would it be the cad converter plugged up??

Probably a coilpack...start with the cheap and easy possibilities. Have someone measure operating voltage of the coilpacks.

thanks for your help. it was the maf sensor

I was gonna say MAF sensor, I had the exact same problem 2 years ago. Last year i had the problem again and it turned out just to be bad plugs.
