1992 Isuzu Rodeo, 203000 miles. Had an issue the last two times I drove it. Drive for 20 plus minutes and come to a stop and the RPM hand bounces up and down and it wants to stall. Can hear a wining hissing sound in engine compartment. Park and let it set and cool and it will be fine until an other 20 minutes of constant driving.

With the noise your hearing the first thing i would check for when your hearing that noise is for a vacuum leak.
