i just finished p&p my TB on my 04 5.3 and i put it back on and started it. It sounded like it was missing for about two seconds and then it was idling a little high and then "reduced engine power" came up on the display. I unplugged the bettery and im letting it sit for a while and im gonna go try it again. What could it be?

 

jesus christ cylinders 2, 4, and 8 are down. WTF did i do.

 

im getting TPS codes right now. why would that cause those cylinders to not work? And how do i fix it?

 

ttt for ya. Interested to see the outcome.

 

Did you take off the senors when you port and polished it?
Make sure the contacts are clean and that nothing got into the motor for the throttle and the tps sensor . Check all wires

 

ok its still doing it and i cant figure it out. Im gonna try to find someone with an 03-05 v8 so i can switch the tb and see if thats the problem. I just dont understand why its doing it. i cant rev it past 2,000 and it takes forever to get there. PLz, any help will be appreciated.

 

i didnt take it apart bc its riveted together and i didnt feel like messing with the return spring. i had the idle air control motor hole blocked with a piece of plastic so i dont think anything got in there. ill check it out though. thanks for the input. i really need to figure this out bc i need to go back to college tomorrow

 

so i guess ill just get a whole new tb and reflash the computer, i hope that will fix it.
