Did the dealer prep guys forget to fill it with fluids?
THat would be funny given the headache he went through just getting the car. HR said the dealership has car they sent them the deivery slips etc. He gets there to pick up and they say we don't have your car. They walk the lot twice looking for it and nada. Mr snick drive home and calls HR saying the dealer didn't have the car. HR calls the dealer and basically says you f'do have the car. Here is the paperwork YOU SENT us. Mr snick gets a call back from HR saying they walked the lot again with several more people and found the car. Give them a few hrs to prep it and go back to get it.
It's chugging because of the extra load through the exhaust. Get the muffler bearings replaced as it's likely too late to just grease them up.
THe manual said it was one of 3 electronic control issues.
