2004 grand prix gt1
The problem is the car is bogging down and
stalling. It started out throwing a code for fuel tank
pressure sensor so i replaced that. The service
light went out but same problem. Since, ive
replaced fuel pump, new fuel filter, and replaced
fuel pump pressure relay and still nothing. A buddy
told me its a clogged cat... It idles just fine. When
not in gear i can red line it all day and no bogging
and stalling out but when i put it in gear and give it
some gas it bogs down real hard and stalls. Any
suggestions to what this might be???
Unplug the Mass Air Flow sensor and she what she does, or I'm thinking possible clogged injectors..
I unplugged the o2 sensor from the manifold and nothing changed. Do i need to unplug the one on the other side of the cat too?
