studdering like igntion miss or what exactly what are you using to control the fuel most likely gonna be related to your tune

i dont know how to explain it, when i give it gas it just studders, but the rpm's will rise? its just like how the other guy posted about him it happening when he was turning, mine only use to do it on turns but now it happens when im accelerating no matter what. and it has a real hard time idling

whats your fuel pressure like. It might be the pump failing its good posibility.

its good for you to check it out and see your fuel pressure at the rail. If its constant and on boost is rising accordingly then it something else

check that all injectors are firing, check plugs, wires, cap, rotor. change the filter.

did you check the fuel pressure? check it.

check your plug gap,you might be blowing the spark out.
I had problems like that and had to go tighter on my gap (.025)
semms to have taken care of the prob for me.

worth a try!

gunna look into that too

warrick

to check if the injectors are firing, you have a couple of methods. take a screwdriver and touch it to the injector, and "listen" to the handle to see if it is ticking.
you can also get a logic probe or an actual tester for it.

If your tune is off it will cause this type of stuttering. I know 'cause my car does it
