My truck spits, sputters, misfires, back fires, and stalls out. It is so bad that the truck barely moves, practically no power what so ever. I had to start it 4 times just to get it onto a trailer to take it in to have it scanned. I had it scanned and it threw codes po137 O2 sensor bank 1 sensor 2, po131 O2 sensor bank 1 sensor 1, po131 O2 sensor bank 2 sensor 1, po137 O2 sensor bank 2 sensor2, po300 random/multiple misfire, po430 catalyst system, po171 system too lean, and po174. Before I had it scanned I put in a new fuel filter, plugs, and wires. Next I'm thinking a crank position sensor. Any help would be greatly appreciated! Thanks

Scan for codes and check fuel pressure first.
