98 TA, M6, idle issue.
98 TA, M6, idle issue. the car: 98 LS1 Trans Am, m6, just hit 98k, mods: lid, B&M ripper, RAM clutch installed by last owner.
the Issue: occurs when car has been running (freeway) for a while, and I slow down to city driving/stop-and-go traffic. after a about a mile or so of rush-hour conditions (constant slow speed, lots of engage/disengaging the clutch), the Temp gauge gets to about the middle (210*) mark, then the car starts to idle at 1300-1500rpms, and wont come back down. I'll get to my destination, turn the car off, let it cool, and back to normal when I restart it. It did this a lot in the summer, and I replaced coolant/t-stat back in August, but it still does it when car gets hot.
Everything else seems normal, not sure what exactly. The plugs/wires are original, so I know its about time for those to go.
Thoughts/Diagnosis?

when i had your problem, it took weeks of goin thru what i thought.
turned out to be a leak on my intake. since u dont have an after market one, check all your hoses for cracks.
