I was having a sputtering problem with my vehicle. I took it into Tuffy at Olentangy for a diagnostic check Jan 5, 2007. After being charged $89 for the diagnostic check, I was told that I would have $650 worth of repairs on the vehicle. These were: new fuel filter - new spark plugs and lines - fuel line flush - and replace rotor.
I went to a different service center and found that I only needed plugs, which were to cost $40. I do not think Tuffy on Olentangy truly did a diagnostic check on my vehicle, and tried to up charge me when explaining the diagnosis.
