Motor does not run right at low RPM
I have a 502 500 hp big block. Motor was rebuilt 2 years ago. Ran great half the summer, then we started having issues at low motor speed. Motor sounds like it is running on 3 cylinders when not on plane. Motor runs great above 3000 rpms. No problem at full throttle. Replaced fuel filter. Had the injectors and fuel rail done. Timing is set and mechanic said sensors check out. We keep thinking bad fuel, but drained the gas and out new gas in it
