well this might not be the right place to ask this but, i have a 1998 dodge ram, and i brought it in to the auto shop in my schoolto get it inspected and it wont pass, i repalced the brakes, oil change, no exhaust leaks, its got and aftermarket exhaust system headers flowmasters, but it will not pass, i ran some codes and it said everything was good.
anyone got any ideas????

 

Well what part of the inspection did it fail? It's not a guessing game you know lol

Do you have working cats in the exhaust system?

 

yeah, and the shop teacher didint tell me what part it failed
