Some times in all gears ever sense I put my stage 3 kit in the throttle seems to be jumpy, what i mean by this is that when accelerating the car feels like I am letting on and off the throttle. I seems to be getting worse. Does anybody know what this might be.

 

when i jumped down to the 2.7 i got the same thing...i think its just cuz the ECU doesnt know whats goin on but it doesnt cause any codes...once you turn the car off it goes away

 

My car seems to do this as well, all stock

 

I think its a result of some hiccups in the Injector flow v. Vaccuum tables. Once I retuned my car with HPTuners all my little glitches were smoothed out.

 

thats what i wanna do, get hp tuners and smooth out the occasional hiccup and get instant throttle when you mash the peddal, i notice if you dont shift a certain way the car like to jump around for a sec, with a tune it should be a good setup with whatever mods you have.

 

Does any body think this may be happening because I have an intake also w/the stage 3 kit.

 

Sometimes these hiccups and you call them jerk my head back and forth, was it that bad w/ your car.

 

I just got back form lunch and on my trip my car began to misfire and run very very bad. I think the car was running on 3 cylenders for a min or two, so I pulled over turned to car of and back on it was running fine again. I think something is wrong with my new stage 3 PCM.

 

Well I pulled apart my fender after work tonight and my MAF sensor was not even connected. There were no screwes in it. I put it back together and it is running alot better. It only does this very lightly at high RPMs now I think that is because of the intake tho.
