1994-1996 (I believe) camry 1mz-fe engines have a metal PS idle up valve. They work very well and don't break off nearly as easy. Just about any Toyota with out a throttle by wire system uses one of these valves. Most all of them use the same treads and a very close air flow through the valve when pressure is applied... so junk yards can be of some help when you need parts at a lower cost, down side to this is they are usually hidden behind something and hard to get at in a u-pull-our-parts place.
