Idle Issue
Ok got a major vac leak solved, don't ever over torque intake gaskets... Anyways my 86 L98 runs fine at idle for 2-3 minutes and then the RPM's start dying down slowly until it wants to quit. The remedy is to lightly tap the gas and it goes back to normal. Any ideas?

Have you:
1.) Checked and corrected any trouble codes?
2.) Cleaned the IAC valve and passages in the TB?
3.) Checked or set the minimum air adjustment?
4.) Checked or set the TPS?
Lately?

2)I took the TB off and sprayed it down good with carb cleaner. However but i think I could have done a better job. Should I take off and clean more throughly?
3)How do I set minimum air adj?
4)Sorry to sound dumb but what is the TPS? Throttle Position Sensor? How would I set it.
Thx for the info

As your new factory service manual will explain, it is in the counting of the flashes of your "Check Engine" or "Service Engine Soon" light.

The more one knows, the less dependent they are on the well intended but misinformed responses. A little independent knowledge helps one separate the wheat from the chaff.
