Redwagon96

Hi, I have 96 3500 12 valve that is beginning to have rough idle and will die if I have been working it pulling my 34' 5th wheel. New fuel filter 1800 miles ago. Truck has
132000 miles After working it and then stoping at a stop sign it seems to have lope in the idle. Not real noticable, but its there. If I let off the accelerator quickly at a stop sign it will die or have that rough idle.

Any suggestions?:

Jim

Just to update on myself. I have 96 3500 12 valve standard cab purchased in 98. I was Indy 500 crash/rescue truck. It has decals displaying Indy 500 1996 and several other Indy decals. Truck had 48000 on when I bought it, now has 132000. I am in process of installing double deep tranny pan and temp guage so I can monitor more closely while pulling my 34' Jayco 5th wheel.
I have been retired 5 years. Got to go early. Was railroad engineer. Finally getting my list whittled down so we can begin to enjoy the 5th wheel.

What does it idle at when hot? It should be at 750 to 800 in gear with the ac on.

I wouldn't be surprised if your rubber fuel lines are allowing air in.
Short sections between frame rail and engine on both feed and return lines.
