    Idle Air Control Valve issue

    I need a new IAC for my 87 Lebaron Turbo 2.2 However, every IAC I find, even from Rock Auto, has the 4 wire/plug configuration. The one on my car is a 2 wire/plug config. I am being told this is an issue finding the part. Any vendor here know of or have the correct 2 plug/wire IAC?

    Those are NS1 and no one makes a reproduction.

    The common failure with these is contamination at the valve and dirt within the planetary gear that moves it.
    If the motor still works (unscrew the clamp, pull the motor out and plug it in to determine) then pull the valve/gear parts out, clean them while gently removing any scratches in the plastic valve insert, wash and re-assemble.

    Note:
    Do not use any grease or oil during reassembly - assemble it clean but dry.

    5DIGITS - you happen to have tricks on disassembly? Ive read of a few failed attempts of tearing them apart and them not working correctly again
