Question
What causes automotive catalytic converter "clogging"?
Answer
Rich fuel mixture and oil consumption.
Explain
Clogged converters increase exhaust backpressure. CHEPQ tools monitor fuel trim (positive trim >10% indicates rich mixture) and oil consumption—repairing fuel system faults and reducing oil consumption prevents converter clogging.
