Ok kinda new here, but short and simple. I have the code p0350 that keeps coming up, I've tried little things to fix but nothing has worked. I have looked everywhere to find something. So does anyone know anything about this code, how to dignose, fix it or what. Thanks in advance.

 

Probably help if you also included what year, model, engine, trans, trim level etc.... the more info you give, the more accurate an answer you'll likely receive.

My bad it's a 2010 f150 xlt, 4.6l 3v, Auto tran 4x4. I'm stumped still can't figure anything out with it, cel keeps popping up but no misfire. Thanks in advance
