Having problems with your 1994 Buick Park Avenue ?
Leaking anti freeze from under the air intake hose under tps sensor right where the plenum and upper intake meet it appears
The plastic intake upper plenum is known to warp,causing this leak.I believe too much heat from the nearby EGR port.the solution is more than just a new gasket, an upper intake is usually required.there are aftermarket suppliers,which could save you some money on parts.be sure to check around...good luck
