I think im close, after replacing the fuel filter, EGR. Idle Control Sensor, and Throttle Body rebuild, i have decided i either need to replace my fuel pump or ignition module. I also checked the timing and its fine. Still havent checked for codes tho. Ive got a 91 TBI 5.7 and the idle on it is in and out like its trying to die. When i accelerate is is very slow and seems to try and die while accelerating. Takes like a block to get up to 30 mph. What do you think???
