Exhaust sputter
Hello all, I am posting this for a friend of mine. He owns a 2003 fleetwood pace arrow 37A. Chevy workhorse 8.1 L. He recently noticed a sputtering noise from the exhaust tailpipe at idle. No noises ...

Depends on the type of sputter. First thing I would do is make sure all the spark plug wires are pushed on all the way. The 8.1 was notorious for spark plug wires coming off. The problem was that because of the short length of wire, it was very easy to not install the wire all the way. As a result, they would come unplugged. Its not a persistent problem, once they are plugged in correctly, they do not fall off. Its just a matter of difficulty getting them plugged in all the way. If someone is just the least bit lazy, they will miss one or two. You need to make sure you feel the snap down into place, rather than just pushed on.
