CEL and Traction light
I recently installed Tsudo UEL headers onto my car, after a couple of weeks I got a CEL and traction light. The code is P0171, I've replaced my fuel ratio sensor and cleaned the throttle body. Can't seem to figure out what wrong. I also made sure to get an OFT2 tune with the headers as well.

Maybe if the car was slipping with the small increase in power. Maybe caused by the tune but both are unlikely. CEL might be from the tune. Also might be from the TCS light. |

Traction light usually comes on with CEL. P0171 is a lean code. Check your header install for exhaust leak first.

Do you know how to log or look at live engine parameters with your OFT? That would help.
Also, what tune did you load to the ecu?

P0171 turns on both traction light and CEL. Seems like an exhaust leak to me.
