quick question,, surging
when the truck is kinda cold,, but not when you very first start it. when idling and only idling you can barely here it surging just a tiny bit. It won't do it in high idle mode. Its so small probably only I can hear it. Only at times you can barely see the tach doing it. No codes present. and doesnt do it all the time. Once it warms up completly its gone. any ideas?? but just thought of something, usually I add "diesel clean" to every tank,, this tank i didnt'. The octane where I get my fuel is only 40. Could this be it,, and lack of "diesel clean" Really not a problem, just wondering,, thanks Herb
