Exclamation

So i know this is an ancient thread at this point, but I have the exact same truck and issues, was there ever a remedy?? I've dumped more money in the truck than it is worth to figure it out and still nothing. ANY help would be GREATLY appreciated!

Thank you!!
Jake

I believe there were several solutions depending on how your specific trouble shooting resulted. Mine is a combination of bad gas and clogged catalytic convertors, but all that trouble shooting may caused me a burnt exhaust valve also.

have you tried pulling your codes yet??
if you have not change plugs and wires (mini tune-up) check fuel pressure, change fuel filter, I would do the little inexpensive stuff that probably should be changed.
but I would read the codes first IF any
