An engine misfire might seem like a minor performance glitch that you can ignore for a few weeks, but the unburned fuel escaping your engine cylinders has to travel somewhere. That destination is your exhaust system, where it can cause immediate and costly problems.
Your exhaust system relies on chemical reactions to transform toxic gasses into safer emissions. When a spark plug fails or a fuel injector sticks open, raw, unburned gasoline dumps directly into the exhaust pipe. The catalytic converter operates at incredibly high temperatures, and when that raw fuel hits the red-hot internal ceramic honeycomb structure, the gasoline ignites inside the unit.
This internal ignition creates intense heat that literally melts the precious metal coatings and ceramic structure inside the shell. The internal passageways fuse together, blocking the engine’s exhaust flow. This creates massive backpressure, causing your vehicle to lose acceleration power, sputter, and trigger a flashing check engine light on your dashboard.
Fixing the ignition problem early protects your exhaust system. If the internal component has already fused together, a complete catalytic converter replacement is the only way to restore your engine’s power and pass emissions checks.
If you have been experiencing engine misfires or other problems that may signal an issue with your catalytic converter, schedule an appointment for our skilled mechanics to evaluate your car. We can diagnose whether you need catalytic converter replacement or another solution. We can also advise you on proper maintenance protocols to avoid premature catalytic converter replacement and other common problems. Contact us today!
