truck bucking

dixiechick1968 · Oct 13, 2011

Recently, i replaced my transmission. Since that time, i have been having a problem with the truck bucking when warm/hot. I have replaced the wires, plugs, distributor cap, rotor, and just yesterday, the fuel pump. Problem has not been solved. Prior to the transmission change, my truck ran beautiful. Any idea what might be going on??? I appreciate your input.

Define bucking... Is it trying to throw you off? Lol jk but a better definition would help.

Ha-Ha-Ha....your funny. It starts and runs great. And then when warm, it starts spittin and sputterin like I am out of gas. I have to pull over, put it in neutral and hit the gas until it clears itself. I am ok after that for a little while. Does this make more sense??

Fuel filter?

Sounds like you have a fuel delivery problem for sure. Dump some Lucas injectors cleaner in the tank. Also check all your fuel lines from tank to engine and bleed the fuel system. Finally if none of this helps.... I'm stumped. Could be dirty objectors. I had a similar problem in an s10 turned out to be a fuel control module that had gone bad so look into that as well.

doesnt the auto trans have something that connects to the throttle body?

b/c it only does it whens it warms makes me think of some type of egr or similar system

Try this. When it is warm shut it down and remove the aft o2. Sounds like it has a possibly clogged cat. Try that. Also dunked check fuel preasure at the intake. Make sure its getting enough fuel. Do you get any mil light codes?
