Oh no, the dreaded check engine light came on! Searched for someplace really local as the car was shaking. While looking at their website thinking "this is going to be expensive" I found a coupon and decided to go in. Chris at the front desk was very nice, greeting me and letting me know they could certainly diagnose that day.
They were very thoughtful and involved me in the process asking about the car history, recent events to get to the root cause of the issue. All said, they determined it was more than likely mis-firing injectors. Cleaned the injectors right then and there, and no issues since. I appreciated their communication, consideration, friendliness and no up-sell on things I didn't need. Thank you Doctor Auto!
