If anyone can point me in the right direction to fix this problem i would be extremly grateful

...also my car doesnt have any trouble idleing, accelerating or starting up? thank you.

got the car up and couldnt see any charred black spots on the exhaust or headers. and just curious if it was leaking from where the headers mount to the heads would there be a pretty noticeable sound coming from it? ive sprayed the intake manifold and intake and pretty much the whole engine with starting fluid while it was running and it idled perfect. i also have a p0153 o2 sensor code?...which i just found out :/
