Try vacume hoses. Check all the routing

yup, sounds like a vacuum hose is loose/ not put on

almost definately a vacuum issue. check/replace PCV valve if needed. check ALL HOSES and make sure they run to the correct locations etc.

if you haven't already, do it now, but do the G2IC "Teg Tips" method of cleaning the IACV. that'll help any idle problems that you may have had before.

How did you blow your head gasket? you know before you put it back in you got to resurface the head so it doesnt warp, that could lead to a loss of compression, but yea check all i/m hoses, maybe a compression check too

ok fellas found out and fixed the problem, it was my valve adjustment. when my mechanic did the head gasket he didnt readjust the valves so i took it to another tech and he redid them so it idles nice now.

thanx for all the input fellas
