I had an intermittent ""check engine soon"" indication that would come on and and the truck would run rough. I did some research ahead of time and John at Performance Wise nailed it over the phone with his diagnosis. The job was not as bad as it could have been and he called me twice to update and adjusted the bill accordingly. I also inquired about some other work and he was honest and candid, saving me money on a vehicle with 200k on it. I dropped the vehicle off late afternoon and the work was done the next day by Noon. The shop is clean, their policy is honesty and the price is fair. I would use and reccomend them. This post will be updated.
