I would say just do it yourself, then, when you are done, take it to autozone and get the codes checked. Should be all clear. 267$ for the part? You could have it OVERNIGHTED at 55$ for 1/3 that price...

I find it kinda funny that the part from autozone is 67$ and the price they quoted you is a nice even, flat, 200$ more than the autozone price...

Never take your car to a Chrysler Dealership UNLESS your car is under warranty...
