I have a 2010 crosstour with 131,000 miles on it...relaced the alternator 3 days ago...ran fine after..Now it is misfiring and engine light is flashing..Any ideas ? Thank you.

Is it possible that before you replaced the alternator, you had the vehicle jump started? And perhaps whoever jump started the vehicle they did it wrong? I've seen similar problems when someone jumped POSITIVE TO NEGATIVE or some tow trucks will accidently use 24v instead of 12v. Or perhaps you used a battery charger and accidently hooked it up wrong or had the wrong setting?
