Ground wires effect the iacv?

[toointoxicated62]

I was cleaning up my harness and i think i may have the iacv to a different ground then it was suppose to? ive read that the ecu controls it using the ground?

The motor wont idle in one area, it floats around between 2k and 3k. Disconnecting and pluging the line that runs to the iacv from the manifold makes it idle at 1.2k. Help please

you read right about the ecu controlling things by supplying ground to solenoids. so if you grounded it it would be on constantly.


why would it idle at 1200 rpm though with no air going to iaa unit. where would that air come from?

The motor still recieves air threw the throtle body or vaccum leaks lol. What else is controlled using ground engine whise.
