Try cleaning the salt and pepper plugs. Google it, there is a how to.

This has helped me in the past, also a good tune would help so they can pull some fuel at idle, probably running rich and computer keeps trying to add and subtract fuel causing surge.

have you checked codes?

Just wait for the tune Moe. It more than likely has to do with ur setup + the stock tune.

I'll tune it for you Moe. [Big Grin]

lol after today i give up lolwas jus gonna see what the tune does ne ways i got the car to not turn off tho it originally wouldnt even stay on

Stock eec have a hard time with the 42s around idle with no tune but its doable.

Convert to a slot style blow thru maf and a tune never look back.
