HELP!! V8 runs rough when warm
I have a '95 D-90 that seems to run rougher upon warm up, It will buck, sputter, internal backfireing sounds, poping, etc and have no power. I also have to crank a while to get it to initially start. I have replaced the fuel filter, fuel pump, spark plugs, cleaned the grounding points around the coil/amplifier. Any other ideas??
