Doesn't sound like that is going to fix my issue.

sounds like the map sensor vacuum hose is unhooked or plugged at the throttle body.
or a ground is loose or wires pinched that have an injector hung open.


the map sensor is that square box in the upper left of your picture just above the egr valve that is missing the vacuum hose.

are you sure you have the firing order right?
