I'm still having some odd problems with my truck. I fixed the rough idle, thanks to you, but I still have an intermittent loss of power. There are days this thing runs almost like a NASCAR truck and then other days it seems like I need to be towed; has anyone else had this problem. tks in adv

Thats simila to mine. I doesn't have as much power as it used to but on same days it runs great. Usually runs a little better at night...or maybe its my imagination. But it definetly has lost some power. Its not as strong taking off in the lower RPM and torque band.

Changed your fuel filter lately? Similar reports claim that a new filter corrected the problem.

 

Mine has been changed. As well as plugs and wires.
