P0171 Fuel Trim System Lean ECM, PCM


.I'm guessing that is saying I am running lean? My wideband is reading around 14.5 under normal driving...WOT is around 13

I also had another code...P2261

Cylinder 1 injector circuit low....



any enlightenment would be greatly appreciated..

thanks

 

loose injector connection.

the 171 code is from your fuel trims. nothing to do with afr

 

doesnt mean your running lean.

it means that fuel trims are working extremely hard to KEEP you from going lean.


on a custom tune are you?

 

yes, used HP tuners...any suggestions?

 

you have HP? or someone tuned it for you?


do you know what your trims are running at? sound tune related.

 

It could be your injector code throwing the fuel trims out of whack. Fix the injector lead and your P0171 might go away.

If it doesn't, retune your MAF.

 

yeah unfortunately I didn't do it...I was just hoping to get a general idea of how serious this could be..thanks all for the input

 

dont worry you should be fine... dont drive till you get the issue resolved extended driving may cause damage. but who ever said to fix the lead to the inj is on it thats were you need to start trace the wiring from the inj and make sure theres no rodent damage or loose wires or broken inj clips hope this helps and gives a place to start...
