Here in Ontario where they bust your balls as well, here is a little trick........Put some Isopropyl alcohol in the gas tank (rubbing alcohol) prior to your test ( let it run through your system prior to your test.) One litre or roughly one yankee quart for a tank full of gas. The alcohol will make the engine run lean because the fuel is oxygenated. After the test fill with fuel to diluite the alcohol. Here up north in the colonies we use alcohol as a gas line antifreeze. Isopropyl for fuel injected and methyl hydrate for carb engines. The only good thing up here is that e-testing not required for vehicles that are 20 yrs or older.
