ok, well i guess its not vapor lock lol. when the head was off, they changed all the valve stems and did basically the whole nine yards on the engine. I had a full gasket kit, so I told them to replace whatever they came across with a new gasket in the kit.
I use fuel injector cleaner once in a while, but it never seems to really help with this problem. I will buy the techron stuff and do what you said.
lets just say fuel injector cleaner doesnt solve the problem. then am i looking at dirty injectors? or major carbon build up in the intake valves?
