Came in with DTC code saying there was a misfire on #1 cylinder. Was told I needed new plugs and fuel injectors cleaned. Cost was $790 which I feel is excessive. Drove car home (25 miles). Parked vehicle. Touched accelerator while idling and engine speed quickly increased to 2500 rpm. Had to shut off key to slow down engine. This reoccurred every time I touched the accelerator while in Park. Took back the next morning, second trip, and was told it had to stay overnight to reset computer after reprogramming. Was given a loaner. Came back third day and vehicle was fixed. A plug replacement and injector cleaning should not be this complicated, this costly, or take three days to complete. . The vehicle worksheet said one plug was cracked and one plug wire was separated from the terminal. In my 56 years of driving and maintaining my own vehicles, this happens when plugs are incorrectly removed. We have been buying vehicles from Bergstrom since 1999 and until now have been very happy with our choice. We are planning to purchase a new vehicle in the near future and for the first time since 1999, we may not purchase from Bergstrom.
