hmmm, just can't keep the thing running right.... well, here is the run down... when idling after first starting it up it idles rough and the motor shakes alot.... when below 3000 RPMs (not in boost) it feels like there is a slight misfire, and in 4th and 5th gears and not in boost the car doesn't want to accelerate hardly at all.... but when I'm in boost it feels fine, no misfire or obvious power loss.... the only thing that occurs when in boost is a chirping/ticking/clicking/annoying sound.... the sound comes from the left side of the engine bay (driver point of view), but when there isn't a load (in gear) on the car it doesn't make the sound or misfire, revs up perfectly...

also, along with hearing the sound, I can feel it also.... nothing big but I can feel a very slight jerk in the shifter and gas pedal...........
