My 2011 F250 6.2 will fall on its face off the line with low throttle but if I mash it, she'll scoot. The only codes that are popping up are rich on right both banks and permanent break with the gas return. Trying to figure out and the boss wont take it to the dealer to get her fixed . 125k and running strong other than that.

 

What are the codes you pulled?

 

Right bank sensor one and two rich, evap system small leak (fixed that with a new gas cap), and permanent break. Give me a couple hours when we slow down with our call volume and I'll give you the code numbers if that's what you're looking for lol.

 

bad o2 sensors?

Codes will tell better.
