After months, I finally found time to get this car I bought running. Turns out it needed a fuel pressure regulator, since it was so badly flooded from the leaking diaphram that it wouldn't even start. Anyway, I got everything buttoned up, then I notice it has a really high idle, like 2500 RPM. After looking at the throttle body, I noticed whoever had the car before me cranked the screw all the way in to set a high idle, which I then corrected to match my firebird's throttle body. Now, the thing hunts from 600-1500 very rapidly, and stalls. I plugged a bunch of vacuum leaks from the evap canister port and cruise control hose, so that should be good. No codes are stored. Any ideas?

bad tps, or idle air value, throttle body clogged, or down to the needy greddy if none of those work, change ur distributor. I changed every part imaginable that dealt with the idle control on the car, turned out to be a bad distributor.

Looks like somebody already changed the ignition module- found an old one in the back of the car somewhere. Cap and rotor are old- hope it doesn't come down to actually changing the distributer itself. Anyway, I calmed down some of the hunting idle by replacing the missing PCV line- that shouldn't have much to do with it since now air is coming from the valve cover instead of the atmosphere. The car had a dead battery- will it hunt during the "relearn" process?

My car had a hunting idle and stalled when it had a lean fuel condition. The hunting is caused by the fuel mixture swinging from lean to rich as the ECM trys to correct. Replace the O2 Sensor. Measure your fuel pressure.

reman distributor put in mine was 100 bucks. Or it could be a bad pick up in the distributor.I was unfortunate because my whole distributor was bad, so i just couldnt replace the pick up coil itself for 20 bucks. Make sure your connector to your tps is still good, you rarely have to ever change them, but mine was bad, so i had to replace it. All this went down when i bought the car with only 69k original miles, the car sat forever, and wouldnt idle worth crap, and so on and so forth, its been a money pit ever since.
