1987 Toyota 4Runner 22re non-turbo. I have an green electrical plug under the intake manifold I do not know where it plugs into. (See first picture) it is part of the wire bundle come from ECU. other electrical green plugs are properly plugged in. (See pictures). Vehicle runs, but has fluctuating idle, will not pass emissions idle carbons, and losses power as motor increases to warm up (I believe this a different issue) does anyone know where this plug goes to or is not used? Than

I don’t know what this plugs into

Other plugs are correct

Correct plug

Idle air control plug??

 

I’m pretty sure the idle air control works off vacuum

 

Whatever you say.

My '87 22RE idle air control has 2 air hoses, two coolant hoses and an electrical plug. Vacuum?? Not really.

Typically safe to assume this era wiring goes to what it reaches, while noting the tell tales of the kinks and bends.

 

thanks. I’ll check that

 

I have the same model with the same problem and Ive been looking at the same wiring bundle unable to find where two wires and a hose go... Did you ever find some peace in this matter, lol. I can't figure it out and it starting to feel like Ive been at it... way to long for this kind of thing, lol. SOS
