OK so I swapped in my jdm gsr on sunday night. The engine started up but it idle'd at 3k rpm's. So i figured..honda=iacv...swapped the iacv for a known good one. Now the idle will bounce from 1-2k. The car was running lean so i had to retard the timing...the idle still bounces from 1-2k but slower. I'm using the skunk2 gsr manifold is there a vaccum problem somewhere? Ignition timming is off? i drove the car and it has a hesitation after you get going about 10mph and then is steady and the tach bounces all over the place but the engine revs steady so that points me back to the dizzy. AHHH any help appreciated. so so confused
