Check the hose from the valve cover side to the intake manifold. Check underneath, it likes to crack there. Also check the hoses going to and from your idle air valve, and all vacuum rubber in general.

Good luck!

You were right on the money with that! My linkage was correct, but the little wheel on the idle switch was notched out. It was kinda hard to tell.

The car was still stalling afterward. Idle was MUCH nicer.

Ironically, It has not stalled in 2 days.... I cant get the symptoms to come back again. It has done this once before about a year or two ago, and I cant remember if I fixed something or it went away.

Meanwhile, I am going to remove my vac. lines one by one and inspect. Im also due for a cap and rotor. I will save this thread and post again when my symptoms come back.

Thanks
