I had one that blew a liquid filled motor mount and the A/C pulley cut the hose from secondary air pump, causing it to on/off spiratically. The pump may come on on/off as well as the level control, but there may have been a recall I believe on the pump. I don't have the info here, but it sounds like something like that. if it sounds from the right wheel well area, i'd check the secondary air pump, hoses and curcuit.
