ok so i was able to take a look and the bolt is a bit rusty but its tight and the wire looks ok the plastic sheathing is a little broken about 5 inches above the bolt, my day off is tomorrow so im gunna heat up my garage and pull the bolt off and clean it up hopefully this does it, any other suggestions?

 

Disconnect the battery before you do anything.

Clean the PCM connectors while you're there.

Check the O2 harnesses for any damage, maybe one is resting on the exhaust, etc.

 

ok, so i pulled the ground(took no effort to loosen) and cleaned it, wrapped some electrical tape around the breaks in the cover, globbed on some di- grease and wrenched her back, no fluid in the pcu plugs, did find pass sides post cat o2 to be really close to the body heat shield and seen some bare metal marks like some1 scraped away at the heat shield to make room so i just wrapped the area with tape. all plugs were tight and wires looked dry and clean.

 

Was there any improvement or too early to tell?

 

to early, started drinking in the garage with the superbowl on so im not driving anywhere, ill cruise in the am, thanks for your help this forum is awesome!!!

 

ok so bit of an update, hasnt thrown any codes but today after running some errands it started bogging out at like 1/4 throttle quite a bit then cleared up, then did it again 10 mins later, like its starving for fuel unless i stomped on it, hearing alot of noise from the gas tank, im guessing fuel pump, its going to the shop tonight im done with it...

 

so after putting some fuel treatment in it over night it is running better, i think i got a tank of bad gas, but now im throwing code p0152 i have no clue whats going on with this truck im just about done with it, any advice?

 

P0152 2/1 O2 sensor shorted to voltage.

Something seems odd with that O2 sensor - or the wiring.

 

I have checked the wires and connectors 4x already, they were fine, every couple days its another code im lost
