Have a buddy with a scanner. Had him hook it up and both fuel trims are negative but the ltft is stuck and will not move. This is at idle.

 

Your fuel trims are way out. LTFT should be less than 10% Either the fuel injectors are leaking, or something is restricting air flow causing over fueling.

 

I saw that but figured if that were the case don't you think he would smell raw gas at idle and the throttle tip in off idle would be stumbling a bit on acceleration with some black smoke? I would think if all or a couple of injectors were leaking wouldn't that also show on a rail test as a drop off of the static held psi on the rail? The other thing is no DTC pointing directly towards the injectors? I ruled out airflow as a problem because he said in the first post drives normal off idle driving? whatda think grime?

 

Was out of town for 2 weeks.
Stalled today for first time. Only codes are
p0172 and now I have a p013a bank 1 sensor 2 oxygen sensor.
It barely stalls so its hard to read live data while it happens.

 

by restricted airflow do you just mean going into the engine or could it also be a clogged cat?
the airfilter is clean and there is nothing blocking the intake, maf looks fine in live data as far as i could tell.

Otherwise is there any chance the fpr is actually bad?

 

Anything? The only decent shop in town is backed up 3-4 weeks.
