Stalling. At wits end!

What other things should I replace while I have the intake manifold off?

Might not be a bad time to look over the Knock Sensor.

Speaking of OReillys though, have you tried taking it to a place like that and having them hook it up to one of their diagnostics/code readers?

I asked them to hook theirs up to my '01 not long ago because my idling VX had been feeling different than what I'd become used to. We were able to watch various real-time sensor readings to see if anything looked abnormal, although we didn't really see anything that looked out of the ordinary. I verified this by taking it to a local auto shop with a more advanced diagnostic machine and saw nothing on theirs either. (I'm thinking at this point that the "rough idle" sensation I'm "feeling" is possibly worn motor/trans mounts.

If you take your VX to Oreillys though and trying running it with the MAF hooked up and it stalls then and there, maybe one of the sensor readings will make the cause obvious? Worth a try anyway since they charge you nothing to do it.

I'd replace the 2 o-rings for the hard coolant pipes. They have a tendency to get brittle and fail, leading to a very, very slow coolant leak that's very hard to pin down.

The EGR tube runs through the manifold. I'd clean it while apart! There's a YouTube vid on how to do it.
