Well, i have had some idleing problems for awhile now. Car ides real bad when cold, and idles bad but will idle when warm. Plus on average 10-11mmhg for vaccum, and i have noticed a small amount of smoke out the exhaust.

I have tried everything.
Check MAF
Checked MAF wiring
Checked injectors
Checked vaccum leaks
Check idle valve
checked countless other things
compression did check out at 153psi in all 4 cylinders

but i removed the intake manifold and it looks like there is some grimey liquid building up around cyl number 4, could be coolant and oil i susspect.

can i still get a good compression number if that gasket isnt leaking that bad?, and still cause a bad idle?

I dont want to redo the headgasket and this not be it.

What do yall think headgasket or not?

if you have only 11 inches of vacuum then this is your problem. at idle it should be ~21. check vacuum hoses and gaskets such as IM and throttle body.
