Codes P0068 and P0101 engine power reduced

Question

I brought my 06 chevy mainly to the Dealer to flush the coolant system and get an oil changed, the car was fine but when I picked it up from the Dealer the car shutting off and the engine was shaking and could seem to find rpm, so they said that the throttle body needed to be cleaned, so I brought it back to get that cleaned, took the car home but the next morning same thing happened, a lot of smoke was coming out of the pipe, engine was shaking and would stay on the usual rpm, then the check engine light and the traction control light came on and the dashboard displayed engine power reduced.
I scanned it and I got codes P10068 and P0101. Could this have been because of something they touched during the oil change process while it was at the dealership or is it just a coincidence??

Answer 1

HI there

P0101 is for the mass air flow sensor, it's unlikely this would be caused by the flush unless they didn't get the connector plugged in tight.

P0068 is a result of the code or problem with the maf sensor, I would replace the maf and then clear the codes and see if the code comes back.
