So my 02 starts fine and runs good for about 5-7 miles then it bogs down, you can smell fuel like its running rich and if you stay on the pedal it will stall. Engine was throwing all kinds of different codes. I think I've treated them all. I have changed plugs and coil packs, installed new fuel injectors, throttle position sensor and fuel pressure regulator. And I just today swapped out the ECM and the problem continues. What am I missing???
