Could be, but the other way around. The vibrating engine can break loose air hose and other fittings from the cat. Plus vibrating engine indicates the engine is running crappy (duh). A bad running engine dumps gas into the cat clogging / polluting it.
Vibrating engine usually indicates mismatched cylinder problems "a" bad plug, sparkplug wire, cracked distrib cap, worn valve or rings.
