That's not much info to go on, but... The 3.2 is notorious for having floppy timing belts at around 100k miles. This is normaally caused by owners not properly maintaining the engine properly because "Hondas last forever". Of course it's really an Isuzu so that doesn't wash.

Anyway, get someone who is qualified to isolate the problem to look at it soon. If I'm right and you drop or break the timing belt, you'll bang all the intake valves, and that equals $$$$$.
