Your car passes its emissions test thanks to the work of the Cadillac DeVille catalytic converter in reducing the toxic levels of the pollutants in the exhaust gas. It doesn't perform as well when a misfiring engine causes it to overheat or when catalyst materials melt inside. Exhaust becomes trapped, creating backpressure that makes your engine quit. Don't let it reach that point by installing a new catalytic converter for Cadillac DeVille from AutoZone.
