Engine runs rough.
I have a sb 350 that doesn't seem to idle well like it misses. I recently rebuilt it and it ran great until I blew the trans pump. I replaced it with another tranny and it seem to run fine except for the slip from first to second. The car idles real rough I changed fuel filter, cap, rotor, coil, and even rebuilt the carb. I can chenged idle mixture screws, and timing but niether seem to help at all. When give it more throttle it seems to smooth out some. The car also dies frequently at low rpms under light throttle. I checked the plug wires many of times and they all seem to be fine. What should I check next fuel pump? Ign. module? I'm begining to think this engine is cursed with all the problem I have had with it.
