I just recently put a unorthodox pullies, skunk 2 pro series cam gears, and an ant exact flywheel on my H22a swap in a 99 civic. Now its idling funny, after driving a while it fluxuates from about 500-1100 rpms and kinda pulses. sorta voom vroom vroom vroom. Cant figure it out, thought it was a vacuum problem but couldnt find a leak. Any help???
