Having problems with your Chevrolet C3500 ?
2000 Chevy c3500 2wd. Im having a low speed miss at constant throttle, almost to the tune of a backfire. If I put it to the floor the truck pulls hard and shifts fine, it idles fine as well. The check engine light is not on. It has 120000 miles and has a 2 into 1 flowmaster dumped just before rear axle. The exhaust gets really hot which makes me think converters.

Check your throttle body ,, it may need servicing,, or it could be the injectors and plugs,,,, if not those then your problem has to be fuel related..
