ahardb0dy Posted August 26, 2011 Share Posted August 26, 2011 Noticed today on the drive home from work the check engine light was on, checked the codes when I got home and had only one, code 45, FSM says injector leak, The FSm says the injector could be leaking or may let more fuel than is needed into the cylinder. I haven't had a chance to check this out yet but could this be why my PF sucks fuel down so bad?? I know our PF's aren't the best on gas but mine is ridiculous.

silverton Posted August 26, 2011 Share Posted August 26, 2011 Try cleaning your MAF. You get a code 45 if the o2 sensor sees a rich symptom, tries to lean the truck out to maxium, and still sees that it's running rich. My truck just had this, cleaning the MAF was the cure.

silverton Posted August 27, 2011 Share Posted August 27, 2011 Next time you check your air filter, spray some MAF cleaner on it anyway. Link to comment Share on other sites More sharing options...
