Don, have you tried cleaning your MAP sensor?
You say they won't clear, are you clearing them with a scan tool and they come back on?

 

Use scan tool or disconnect the battery for awhile.

 

I will try unhooking battery

 

No i havent and will try with scan tool

 

OK unhooked battery for about 13 minutes and reconnected battery light went out but came back on after about 2 minutes with different codes

have driven truck about 25 miles still not running very good
I don't know how to fix map censer?

PS I'm using BlueDriver for my scanning

 

You have a short in the wiring for the O2 sensors somewhere. Given that it affecting both O2 sensors..... gotta be somewhere upstream from them.

 

Any suggestions in where to start to find short?

 

I don't have wiring diagrams for your truck.... but, as it is whining about ALL the sensors, gotta be close to the source.....
