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

Stonum Automotive Answer:
Let's get this out of the way: a leak in your exhaust system could be deadly. If Longmont 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 Stonum Automotive. 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 CO 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 Longmont drivers. Many Longmont 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 Stonum Automotive 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 Longmont drivers ignore: It might just be illuminated for a condition that could lead to catalytic converter damage. Have your technician at Stonum Automotive get to the bottom of any Check Engine light situation.
