My car was running great. I parked it for a couple hours for a cookout and when I went to start It ran like crap and shut off. So I looked at my arc 2 controller and noticed that I had moved the settings as I got into the car. So easy enough I put them back and the car runs terrible. It doesnt make sense it was idling great before. I've moved the setting before on accident and never had this happen. The car will not idle, the arm-1 02 gauge shows that the car is always running rich. It will not dither back in forth at any RPM and the only way to drive is to keep my foot on the gas. On the highway it ran ok and under accel but at low speed or idle it bucks and shuts down. It doesnt make any sense, and while driving it I tried adjusting the settings and it doesnt help. I'm still getting an airflow signal on my scanmaster3. The car does react to changing the MID setting which always stays set at -7clicks. Please help I need ideas for troubleshooting. Did I damage one of the pots in the ARC 2 unit by turning them accidentally?
