Brought in my car to Lamb Nissan for service after a local mechanic could not figure out what was going on. Lamb quickly diagnosed the issue and fixed the car. Evidently, the problem resided with the catalytic converters. Unfortunately, Lamb Nissan service opted to cut the heat shields on the car while installing the catalytic converters. I expected more precision workmanship from the dealer and was disappointed because I was not told the heat shields would be cut.
