Codes 17544 / 16555
Got a 5-hr trial flash of Revo software. After 2 hrs of run-time, with oil temp in good shape I took an on-ramp at WOT, shifts at 6k or so but well under redline. After merging onto the highway, CEL. Car continued to drive normal w/good boost.
Took it to the shop that flashed the software and they pulled the codes:
17544 P1136 035 - Bank 1, mixture adaption (add.); system too lean
16555 P0171 035 - Fuel trim, Bank1; system too Lean
They cleared the code and I drove for 30 more minutes w/no issues or CEL doing several strong pulls. The shop said it could be a minor vacuum leak or pressure leak but wouldn't the issue replicate itself?
Did a STFA, but didn't find any posts with both of the above codes. Thoughts / advice? Thanks in advance!
