If excessive exhaust system back-pressure is suspected or if tail-pipe emissions are too high (while all other systems check OK), remove the catalytic
converter from the car and make a visual check for plugging, melting or cracking of the ceramic grid inside. If any of the visible areas are damaged,
replace the catalytic converter.
