1995 Chrysler Concorde Repair Question
Chrysler Concorde Engine Problem
Did you get snow in the engine compartment? If so, start by checking the serpentine drive belt. Sounds like the alternator isn't working. If the belt is okay, measure the battery voltage with a digital voltmeter while the engine is running. It must be between 13.75 and 14.75 volts. You know the Engine Computer didn't go bad from sliding into the ditch. Chrysler has very little trouble with them, but you've introduced some new variables by replacing it. Most importantly, it's likely not going to idle fast enough and will start hard and will stall when you pull up to a stop sign. If the engine stalls while you're driving at higher speeds, and won't restart until it cools down for half an hour, that's a different issue. For that you would start by reading any stored diagnostic fault codes, but those would have been erased and that valuable information was lost when the computer was unplugged. You'll have to hope the problem will be detected if it occurs again and the code(s) will set again.
