Several intermittent problems solved... including random stalling and weird shifting.. the vacuum T on the rear passenger side of the engine was rotted and had a 1/16" hole in it. It was also collapsing when it got hot. Dorman #47072 from O-Reilly Autoparts is the fix. They had it in stock... everybody else had to order it. Just a heads up... I chased this intermittent gremlin for quite a while. Hope I save somebody else the aggravation.

Nice!
Just to clarify, that rubber tee can be found between the PCV valve and the intake 90 degree adapter and is a common failure item in 91-94 (some early 95 models have been reported) 4.6L engines. It will cause a vacuum leak and several idling problems.

A smoke test is easy + safest way to find a vacuum leak, Do Google ''Youtube Auto smoke test''
