Hi folks. I have an odd idle issue on my '87. It's a Procharged L-98, with the manual trans. I just installed a new 58MM throttle body. The car idles fine and drives fine.....UNTIL it reaches normal operating temperature. Once the coolant temp has gone above 205, when coming to a stop, the idle climbs from 8 hundred rpm all the way to 3K. I then have to blip the throttle to bring it back down. This will occur on most stops. So I gave the throttle return spring an additional rotation to increase the return tension. But the symptom remains. Any thoughts?
