ETC and traction control light both turning on
 

My husband just changed the spark plugs on our 2007 charger. We replaced with Bosch platinum plugs. Before the change the car ran fine. Right after the change on the first start, the car hesitated and the traction control and etc light came on. We shut off the car and turned it back on and everything was fine for 3 days. Today, I started the car fine, I came to the first stop sign and the car starting doing the same thing this time it started to sputter everytime I braked and would feel like it was going to shut off. I pulled over, shut off the car, and restarted and everything was fine. What could this problem be? Why do both lights come on and the same time??

Sounds like you need you PCM reprogrammed. Nothing to out of the ordinary for a dodge car. Doing slight changes to it, even a tune up can throw it out of whack.

how much would something like that cost

like $50-$120, at the dealership.
Dodge product never liked Bosch Spark plugs, don't know why. Go back to Factory Plug, i forgot if it is Champion or NGK for ur car.

Get those Boschies out of there.
