So you and your colleagues collectively are visiting a workshop that doesnt know its December of 2021?
I can guarantee you will post on this forum on why a new throttle body is so expensive in the future too.
Ive owned lots of cars of lots of different brands. Ive never had to clean a throttle body.
However Ive had to change a lot of them in Pakistan because some hazratt ustaad advised such cleaning in the name of maintenance and destroyed the small plastic axle bushings of the throttle.
Btw please inform us of this idiot honda dealership for the sake of people not visiting such lunatics who charge money to damage cars.
