When your Corolla wins major awards from J.D. Power, it's no surprise. You expect it to outshine other vehicles in its class. Engine misfires, jerking and stalling are immediate calls for alarm. While you're looking for the problem, check the Toyota Corolla catalytic converter. If it's blocked, the backpressure prevents your engine from breathing properly.

The chemicals inside the catalytic converter for Toyota Corolla are subject to overheating, which melts them and creates a blockage. Motor oil or antifreeze cause contamination at times, too. In either scenario, your exhaust system performance goes down, your carbon emissions go up and you need to install a new catalytic converter as soon as possible. AutoZone makes this easier by providing Same Day Store Pickup on your online orders. We also offer a Loan-a-Tool Program so you have what you need to do the repair right.
