I was having the same high idle issues. After stalling, when I started it back up the rpms would soar. I just adjusted the TPS last week. It was putting out around .4 - .5 volts at the idle position. The voltage increase as the throttle was opened up was very smooth and steady. I increased the voltage at idle to .8. Now everything seems fine. No stalling and smooth idle. What surprised me is how far I had to move it in order to get it right.

Man am I glad I found this site. Anyway, my 88 is stalling in the same manner. I changed the IAC, EGR valve, tested the EGR solenoid and map sensor to no avail. Am just now getting to the TPS. I saw on another site that it could also possibly be the CPS, but I really don't see how. Let's keep one another up to speed on this one.
