AZ emission laws

so they don't hook up a timing light and check the timing?

I will be taking my mustang down to retest in a couple days. They do not check timing. They will put your car on dyno rollers and run it through normal driving ranges testing the exhaust. Then they will visually inspect the vehicle for the required emissions components. Then they will perform a fuel system pressurization test. They will want to see your tank and lines hold pressure and then gradually bleed off after a certain pressure. If you pass all tests you will be good to go. Good Luck!!
