Let us know. I bet it has to recalibrate itself. Some ECU's after a reset cause temporary hunting at idle for similar reasons. |
Yeah...faults are stored in Non-volatile memory. Unless the cause of the fault is corrected it will likely come back.
Fuel trims will re-calibrate naturally...It usually takes from 25-50 miles for the Long term trims to re-set. You have constant correction of the short term trims though which eventually build a table for the long term numbers to be set
