1985 corvette - idle problems. Hi, I am out of ideas, I have changed the TPS (voltage perfect at .054 idle, 4.0 at WOT), the IAC, new throttle body last year, new Bosch MAF this year, and cannot get it resolved. The car will not idle when cold, and will search when warm in Drive and drop low enough to die. It will throttle up to 900+ down to 350 and die and all in between. Performance and mileage are good at speed, any thoughts to what I am missing? It is an auto with a/c and cruise, all work well. This just came up last summer and I did replace the burn off relay 2 years ago, hoping and praying not it. I changed the TPS over the weekend since a code tripped saying the low side was faulty, no codes now after I disconnected the battery and drove it ~50 miles. Just the idle problems. Thanks
