Many cars fail the emissions test, leaving owners scrambling to make expensive repairs. Sometimes those repairs are warranted – sometimes not. Taking the following actions before you take your car in for an emissions test can keep you from being forced into needless repairs:
- Add fuel injection cleaner to the gas tank.
- Change the oil and air filter.
- Change the spark plugs.
- Check your antifreeze and make sure it’s at the correct levels.
- If your Check Engine light is on, take the car to a mechanic and make any repairs needed to get it turned off.
