my car is idling low (600) since i replaced my head gasket last weekend, it misfires and the vacuum is at 12-14 in Hg. before i took the head off it idled at 1000 and 16-18 in Hg. i've checked all of the vacuum hoses and replaced a few but nothing seems to help. my ex manifold is leaking a tiny bit at the head, could that cause the crappy idle?
thanks
