P0171-Running Too Lean Bank 1
I have a 06 cobalt 2.2 lt there are no modifications done.
I posted about this about a year ago on the issue.
Still trying to find the problem.
When the code pops up the drivability of the car is poor, it stumbles upon acceleration. Usually the only time the code pops up is when i get on it.
I have cleaned the maf, i have checked for vaccum leaks, replaced the fuel filter.
I was reading online the likely causes of this code.
-or fuel pump which is a recall on certain cobalts. I have a letter from the dealer about it.
My only problem right now is i am nowhere near a gm/chevy dealer to get that fixed. I have had the car for two years and the same code pops up at random.
I have noticed over the last couple of months i have been getting a fuel odor but i haven't seen any gas leaking underneath the car.
And from what i was reading fuel odors can come from any one of those three items i listed.
Is there anyone out there that knows of a common problem with this code?
Right now i am leaning towards the front o2 sensor. But i would like some advice before i make my decision.
