I have a 2006 dodge charger srt8 that has been cutting off on me at idle. First time did it no check engine light second time check engine light came on with a code for low battery voltage. I purchased battery for vehicle and car ran fine for a week. Saturday morning car dies again codes 0171/174 come up along with low battery voltage, i replace map sensor on car and 171/174 codes clear out car runs fine for a day or two. Got to start vehicle and it dies again at idle at about 132 degrees. Car starts up and again is running rough. With no check engine light. I am stumped with this right now. I did have an aftermarket cold air intake on the vehicle but that has been on it for over a year with no problem. After doing some research on line, I found out that the map sensors in these vehicles cannot handle the extra air of the cai...is that true? I did replace stock air box back in car and it still shut off at idle. Is there anything that I or dealer may be overlooking with this vehicle that could be causing it to die at idle?
Vehicle has 87,700 miles on odometer and it is not really driven too hard. Also had vehicle tested for vacuum leak and shop found none just the 171/174 codes and low voltage battery codes.
Right now I was forced to take car to another dealership and have them check it out since the first told me it was a bad battery and that's why it died (they didn't even check the other codes 171/174 that were on the code sheet they gave me) I had a local shop fix that. I do not like to have much down time on this car...If this dealer does not solve problem this time, what could be possible culprit?
Any input would be helpful. Thanks

Set Condition: The Powertrain Control Module (PCM) monitors the Adaptive Memory factor (a combination of Short Term Adaptive and Long Term Adaptive). If the total fuel addition exceeds a calibrated threshold for an extended period, a fuel system lean fault is stored. If the total fuel subtraction exceeds a calibrated threshold, a fuel system rich fault is stored. Two Trip Fault. Three good trips to turn off the MIL.
