## NHTSA's summary

N55: Idle Fluctuates Briefly After a Cold Engine Start. Under certain engine cold starts, the engine idle may fluctuate during the first 10\-20 seconds of operation before becoming stable. No faults will be stored in this situation, which will usually only occur at specific engine temperatures, making it difficult to reproduce in the workshop. Unfavorable DME software calibration
