I'm getting a P1125 code that says manufac contrl fuel air metering P1125 control fuel air metering.
This is on a 1996 pickup with 2003 5.3/auto engine. This has only happened on cold mornings right after I take off a few times. If I erase the code it will be fine. It kills the gas pedal once this code sets.
Any ideas on what would be causing this would be great.
Thanks

Load test the battery. This is an APP1 vs. APP2 mismatch DTC meaning the TAC module that controls the electric throttle is seeing too much difference between the two sensors internal to the gas pedal. Most times a weak battery causes this DTC because the TACM and the PCM "wake up" at slightly different times on key up because of a weak battery and the draw put on it by the starter.
If you're no longer DBW, there's something wrong with the conversion tune probably.
I'll load test the battery which probaly would make sense because this has only happened when the temp is only 10 degrees or less out. Its never done it when above freezing.
No i'm still using DBW.
Thanks
