So truck was running like crap... gas mil dropped to 9.5 and had no power. Figured out my torque converter was locked up cause the trans to overheat and blow fluid everywhere... so new trans yay! ... still no fix... put in a new fuel module, 2 new o2 sensors and gutted all 4 cats... cleaned maf, new ff, and gotbmy milagebback and most of my powet back. Still feels like there is a miss at wot but until it gives me a misfire somewhere im not going to go and replace all 8 coilpacks... ok rant off... just had to share... i love to hate to love this truck

 

Get into od and the lay into gas enough but not enough to make it downshift. If it stumbles and cop is bad. Also change the fuel filter if you haven't already.

 

Yeah new fuel filter, new airb filter, cleaned maf.... um all new fluids... seafoam through oil and gas...

 

There is one problem already...'Seafoam'..not so bad in the fuel....but can be deadly in the oil with the 3v 5.4 motors.
