ok so here is where it stands I had my friend who is a mechanic stop over and run diagnostics on the truck motor is fine so i just wasted $400 in sensors I was told to first start by disconnecting and possibly replacing the rear o2 sensor because they are known to short and send messed up signals. We also noticed when shifting into gear or neutral it stalls instantly so he was wondering if the torque converter was junk possibly stuck in lock up was planning on replacing transmission anyway so I will update after messing with the rear O2 sensor and again after replacing the transmission

 

So it is definitely not the rear o2 sensor either I discussed it with the mechanic and we are both certain it is the torque converter stuck in lock up. I will be replacing the tranny and torque converter over the weekend I will update you all after

 

Ok so here is what happened Some how the crank sensor went bad or was bad from the start even though it tested fine. Both o2 sensors tested fine but were bad. The torque converter was completely locked up and all the electrical components in the trans were bad. It runs great except now I have a loss of power which I'm assuming is either a severe vacuum leak or the intake manifold gasket

 

Check the plenum gasket. if that is blown, chances are also good your cat is starting to clog. THAT will most certainly reduce power.
