hardly any power, and kind of spudders on me going through town sometimes, gotta pump the gas to get her going normal again. Had it on the code reader and says all 3 Oxygen sensors are crap..so hopefully change them do you think this will fix it? what else could it be?

 

I was also wondering if anyone knew where the fuel is on these maybe that is it?

 

Three??? You should have two, or four..... california emissions?

Probably plenum is blown, and has caused fouled pre-cat O2, and clogged cat.

 

i looked down into the intake with a flashlight there was just a tiny bit of oil in there, i could still see lots of metal. and there is 3 oxygen sensors, 2 up off each manifold and one behing the cat, and im in canada.

 

where are the grounds on this truck?

 

If youve got codes showing for 3 bad o2's, why are you even asking whats wrong? Lol o2 sensors control the air/fuel ratio in your truck...

Check for clogged cat too, and if it is bad, replace the plenum and cat, like HeyYou said.

 

I just thought it was weird that all 3 are bad, just got this truck. I love it excapt for the gutlessness lol

 

They are probably all three fouled because your plenum is blown, sending oil through your combustion chambers and out your exhaust, all over the o2's. The plenum repair is pretty simple, do that in conjunction with a new cat and o2's and you will love it even more
