OBD Codes

[arabtitalator]

So apparently im running lean on both bank 1 and 2, cylinder 3 is misfiring, lack of ho2s21 switches, throttle pedal position sensor switch circuit low imput.

Just for an idea of how to approach this situation, im assuming for no that maybe replacing my MAF or cleaning it will eliminate some of these problems as for the others i do not have a clue where to begin. Any ideas would be greatly appreciated.

replace the throttle position sensor, it's a $35 part held on by 2 screws. located on the throttle body.

lack of ho2s21 switches

usually means the MAF is toast. Replace air filter as well.

When you're done with all that, disconnect the battery for 15 minutes to reset the car's computer and erase those codes.

If you're still getting the misfire, do a regular tune-up that includes plugs and wires and see if that helps.
