I'm still leaning on dirty injectors.
LOL, I knew you wouldnt let me get outta this without pulling those out, I'm gonna take a look at testing the o2 sensor and if that turns out ok I guesssssss I will pull the injectors and take a look at them :rolleyes:
Edit: I think I might try this first
Causes= code P0171 may mean that one or more of the following has happened:
The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters (K&N, etc.) can cause the MAF to become dirty if the filter is over-oiled
There could be a vacuum leak downstream of the MAF sensor.
Possible SolutionsPossible solutions include:
In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
Inspect all vacuum and PCV hoses, replace if necessary
Check for a dirty fuel filter and proper fuel pressure
anyone have any tips for cleaning the maf and wanna tell me exactly where its located to make sure I thinking of the right thing?
