Engine Idle Rough

[andrewx19x]

Got a 2003 XR6 Turbo manual over a week ago come with CAI Flash tune 12psi centre muffler removed bigger injectors and ever since I got it it has a weird idle the needle go's up and down and listening to exhaust it sounds like it misfires every few seconds still go's like the clappers very happy with it the previous owner had all the work done through AutoTech he said it was to do with what was done to the tune Is This True???? I have owned done up cars before and had similar probs with idle after tune Need Help Note: car has 276.8rwkw this idle prob is when warmed up btw

I would say it sounds about right.

they always seem to pop out the exhauzt every now and again,

mine does it and every other one I have had at work does 2!

really depends how much idle fluxuation your getting mate.

it could be exadurated by the bigger slower injectors perhaps or like u

said, the tune!
