At 72,000 miles, a tune up is probably not necessary, but as a firm believer in maintaining the 41TE transmission, a fluid change wouldn't hurt. As for the throttle body and such, the 4th gen 3.3 and 3.8's are known to get filthy build up there very quickly so it's probable that it indeed needs to be 'serviced' or cleaned. Also, the 4th gen. van's are known for sway bar bushing wear and sway bar link failures. Is there any clunking, whether light or heavy, when going over bumps?
