When you turned off your MAF did you disable the sensor in the DIC or just set the fail frequency to 0?

 

I did both.... but since I flashed back to stock tune with the down stream O2s disabled I'm trying to figure out whats going on with bank2 before I start tuning anything

 

i put a bolt in my EGR also..... i use some copper gasket stuff before i put it in i dont think its leaking... Bank 1 seams good i don't know why bank 2 would have a problem the o2's are just about in the same spot...

 

When Charlie started my VE tune, he just set the MAF to zero. He left the light on. Make sure not to unplug the MAF as our trucks have the IAT in it as well.

 

After I swapped the o2's and ran it for a bit in SD, it ran better. I couldnt figure out how to tune fast enough so I hired Mr. Wheatley to tune it with my HP Tuner. Money well spent for me.

 

I just ran another scan I'm getting mad misfires on cyl 6 guess I have to figure out whats going on in there

 

Any chance the #6 injector is unplugged or not plugged in all the way? That would make the o2 sensor read lean and command the fuel trims high.

 

i did check the connectors on the injectors.......... they looked plugged in.... but I'm not 100 percent if its working everything was running fine .... even had an exhaust leaK from broken manifold bolts and the truck ran better

 

Did you reuse factory manifold gaskets or the supplied? I reused the factory gaskets on mine. You might have cracked the sparkplug or didnt get the wire pushed on all the way. I know the #5 and #7 spark plugs were a pita to get in, #7 had to be installed from underneath. #6 should be relatively easy to get to.

 

I used the stock manifold gaskets.... always they are awesome!!! I'm going to go pull the spark plugs now.... and have a look at them on bank 2... everything on bank 1 is working fine

I put new wires on
I put new spark plugs in.. Delco replacements


If you get a universal swivel and a long extension you can get the #7 and #5 in from under the hump from the top of the truck with no problem
