Thirty-one states in the U.S. require annual or bi-annual vehicle emissions tests, but Iowa isn’t one of them. If you celebrate the fact that you don’t have to pay the testing fees other states require, you’re not alone.
But that doesn’t mean vehicle emissions tests are useless. In fact, emission regulations are intended to help make the cars on the road as efficient and environmentally-friendly as possible. Would your car pass a vehicle emissions test if it was required in Iowa?
Some of the most common reasons cars don’t pass vehicle emissions tests can have a major impact on performance. Iowa may not require vehicle emission testing, but these problems could be costing you money.
Fuel Meter Problem – It’s often caused by a problem with a computer system in the car, the carburetor, or the fuel injection system.
Bad Oxygen Sensor – It’s common problem that can trigger the Check Engine light to come on. Left unchecked, it can cause your car to overheat, interfere with acceleration, and fuel economy.
Ignition System Error – If your car is emitting a higher than normal level of hydrocarbons, you’re not helping the environment. This can be caused by problems with your ignition system or spark plugs going bad.
Vacuum Leaks – Take a look under the hood of your car, and you’ll see lots of hoses can connections your engine needs in place to operate efficiently. Leaks in hose lines and gaskets can prevent your car from running clean.
Fuel Mixture Problem – A problem with the mixture of oxygen and fuel can produce dangerous levels of carbon monoxide. It’s often caused by a failing oxygen sensor or fuel injectors.
Air Injection System Defect – Your car may be producing higher than normal levels of hydrocarbons and carbon monoxide if there’s a problem with the air injection system. It’s not environmentally friendly, and the gases your car releases when this is a problem are poisonous.
Excessive Gasoline Vapors – This is another common emissions-related problem that can interfere with engine performance and fuel economy. Defective hoses, vents, valves, and gas caps are usually the problem.
Just because you don’t have to pass a vehicle emissions test in Iowa, doesn’t mean the testing procedures used in other states are useless. In fact, keeping your car in working order and handling these common issues can improve your gas mileage and engine performance, and be better for the environment.
