so anyone know why.....

Sounds like a mixture of a dirty iac,carbed egr,and a vacuum leak.
clean the egr with brake cleaner and a toothbrush.
( clean the little piston inside,move it in and out while doing so )
Remove the iac,spray it down with cleaner,including the hole.
Other then that,maybe remove the throttle body and clean the passages too.
high idle problems on the tbis are pretty easy to fix. if this was cpi....whole can of worms.

He's got an '89 4.3L.. should be a CPI intake. What entails the whole can of worms? I have close to the same issue, even after changing my MAP sensor and IAC.
EDIT: My tune-up was done last year, less than 10k miles ago

Since his is an '89 and you have a '97 with a completely different injection type, I doubt that there would be a common solution.
