Question:
My car failed its emissions test – what do I need to do?

Tony's Brake and Alignment Answer:
Let's get this out of the way: a leak in your exhaust system could be deadly. If Louisville drivers smell exhaust in the passenger cabin or hear an unusual exhaust sound, they should get their exhaust system checked and repaired. Talk to your friendly and knowledgeable service advisor at Tony's Brake and Alignment. Carbon monoxide in your exhaust is odorless, colorless and tasteless can be fatal to you and your passengers, so don't delay if you suspect an exhaust leak.

There could be a number of reasons for a failed KY emissions test so some diagnostic work is in order. A common reason is that the catalytic converter has failed. The catalytic converter removes some of the harmful elements in exhaust.

When a catalytic converter fails it must be replaced, which isn't cheap for Louisville drivers. Many Louisville folks stop there – but the converter failed for a reason. There may be any number of engine run conditions that led to the failure. It would certainly be smart to have your friendly and knowledgeable pros at Tony's Brake and Alignment diagnose the cause so that you don't end up with another catalytic converter replacement down the road.

Oh, and that Check Engine light that so many Louisville drivers ignore: It might just be illuminated for a condition that could lead to catalytic converter damage. Have your technician at Tony's Brake and Alignment get to the bottom of any Check Engine light situation.
