It can be a hassle to take your car in for service, particularly if you’re unsure if your vehicle’s problem is a big deal. However, in the case of a clogged catalytic converter, you should have your car serviced as soon as possible.
Unfortunately, a clogged catalytic converter can lead to an engine misfire. Misfires are caused by incomplete combustion in the cylinder, which can overheat the converter and cause irreversible damage to your engine. Accordingly, it’s important to have your catalytic converter repaired or replaced before any further damage has been caused.
