I replaced the fuel injector on the problem cylinder and have seen amazing improvements which is great because I have gotten use to driving down a lot of power. Now my drive to work is fun again because when I step on the gas I actually get some HP.

New question though because I am trying to check for a blown head gasket, I am leaking coolant under the exhaust manifold around cylinder 1. At first I leaked a decent amount but in the last week have leaked minimally. I bought a Mityvac MV4560 Radiator/Cooling System and Pressure Test Kit and pressurized the system up to 10psi. My goal was to see any indicator of pressure getting past the gasket into the coolant. I saw no twitch on the pressure gauge but over the course of 3-5 min at idle the pressure rose from 10psi to 12psi.

If anyone has any other techniques to check for a head gasket failure besides just pulling the head I am all ears!

Thanks for your help
