Lamda is the air fuel ratio (AFR) the O2 Sensor monitors. It was probably out of range due to the one cylinder not firing and produced an error. Or the sensor is defective and causing an over rich or lean condition. I am assuming the dealer checked the O2 sensor and replaced the spark plugs and or the coil pack?
Yeah, traded it out for a new one. Dealer was actually pretty good about it. Considering i had to McGyver a tie rod on it with some steel tubing And a couple lug nuts. I could have waited till I got back to Fla, but said heck with it and pulled the trigger on another one. I would definitely say I got lucky the dealer had one and was willing to help me out. Sure had fun while I was there!,
