The AVS is freshly rebuilt by local reputable shop. Car starts and runs great. My problem is idle speed set to idle good when warm is way way too high when cold and choke is closed. Or when set for a decent high idle when cold and choke is closed will cause the engine to kill when motor is warmed up. The difference between warm and cold idle is too wide. Choke pull off is working fine. Mixture seems fine in not too rich. I'm am amateur here. Thanks in advance for any advice. Car is a Chrysler 300.
