Codes

Found the problem cylinders 2, 4, 6 which is the back head had 150 psi reading give or take 10 or 15 pounds. But the funney thing is the front head which is the head that was not showing the missfiring was the head with out compression. Cylinder 1 read nothing cylinder 5 read 20 psi and cylinder 3 read 50 psi.

Thanks for everything

I pulled both heads and had them checked, both where fine. Found that on the frount head the head gasket was blowen between all three cylinders replaced both gaskets put back togther. Now the motor has real good power on take off and sounds good idealing but still serges when throttle is held in one spot. Also still runs ruff when put into any gear. It seams to be related to the low rpms because soon as you push the throttle even a little it starts run o.K.

This car really starting to bug me!
