weird arc 2 problem need ideas - 3000GT/Stealth International Message Center

JayWilRTTT · 07-04-2008, 09:52 PM

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?

you could have a bad factory o2 sensor, your factory IAC could be bad, the maf unit may have gone out or the arc2 controller could have a bad contact (which has NEVER happened).

both front and rear o2's giving me rich condition. IAC value changes when you turn on the ac and goes back when turning ac off. I'm still getting airflow signal from the maf according to the scanmaster 3. I doubt both O2's went bad. Like I said the car has been running great with my new TDO5 setup. I didnt beat up on it before I parked or anything. All I did was turn off the ignition. When I started the car with those wrong settings in ran terrible and then cutoff. The accel settings were at like 16% and the High moved to -12%. I then put the settings back to normal which is
Low+2clicks
Mid -7
High-1
Accel+2
and will not idle and it smells rich even in the car.
