Hey guys,

My car is throwing an occasional P0172 (fuel trim system rich bank 1-B), and C1276 (delivered torque signal CKT malfuction). Today I took it out for a drive. After getting on it in first and second and decelerating from 2nd, it started to sound like it was backfiring (burning unused fuel in the exhaust, my guess). The motor was running smooth but the backfiring sound got very loud and then the motor quit running. I shut the car down, started it back up, ran fine under normal conditions. No new codes, just the two above in history. Any ideas? Im thinking I need the fuel map looked at and maybe adjusted.

thank you in advance,
