I'm not sure what you said there swartlkk. Explain further please.

 

Can you be more specific? What did you not understand? Have you tried searching for any of the terms I have used that have no meaning to you?

 

i have yet to get the codes ran, but another thing that might help narrow this down. If I have a half a tank of gas or been driving for a while it usually doesnt spudder much... It gradually got worse in time it wasnt an all of a sudden problem....

 

I cleaned the EGR today and got the new gasket with the screen in it. Also replaced fuel filter and cleaned MAF sensor. Same result as before with the rough idle and bucking under TCC lockup. I then sprayed under my hood with water and the engine almost stalled and idled horrible. I am now thinking cracked wire so I am going to replace my wires and cap and rotor. Ill keep you posted.

 

or possibly intake leak.... that was another thought in my mind about mine

 

So your problem varies with fuel tank level? If that is the case, then it has to be a fuel supply issue. Have you monitored the fuel pressure while driving the truck?
