I just put a y8 IM back on my y8 head and engine now idles between 4k and 5k. I sprayed cleaner between the head and IM and the engine bogged. The only reason i think there could be a vacuum leak is i don't know why it would idle so high with just a leaking intake gasket. I used a new gasket, cleaned both surfaces of the old gasket material, and torqued the nuts in the correct sequence and to the correct weight. Please help
