What Could Be Wrong???
 

This past weekend I decided it was time to finally finish my buildup of the engine for boost. I have rebuild the engine last year with welded in block guard, rods, pistons, SS vavles, upgreaded valvetrain, etc. The only thing that I was missing was the ARP studs and a nice thick head gasket (Cometic). I started out on Satuday took the head off. Installed the gasket and studs and put everything back together. And now I have a problem. The car idels very low and sometimes even dies. First thing that came to my mind was that there is a pocket of air in my TPS sensor so I blead the cooling system 3 times, but still same problem. I also played with the screw on the TB, but that didn't help much. So what could be the problem any ideas??? The car is not turbo yet.

Thanks for any help.

Anyone wants to give it some thought???

how thick is the headgasket? thick enough to change cam timing? play with the gears and do a valve adjustment and see if that fixes the problem.

sometimes with thick headgaskets the idle is rough as hell depending on how thick it is....

Probably the head gasket, i run 17-23 psi on stock head gasket, no problems(so far) but when i had an aftermarket head gasket idt did f*ck up my idle. but it blew like after 2000 miles, went back to stock no problems

Thanks for the help guys.

I will try to play with the timing and see what happens.
