The motor in the back of the intake will be unplugged.

Error Codes ?

Very hard to advise without all the information,

I think there is 4 plugs/connectors that needs to be disconnected to remove the IM,
And so, there is approx. 4 plugs need to be re-connected.

Not including the Coil Plugs,

Start again, and spray them all with "Contact Cleaner, and make sure they clip in when re-connected

The error code is p0660

That one on the back of the plenum sucks. Chopped up my hand many times on that one.

Only has it on LY7.

In regard to what is happening, there is a small motor, in the back of LY7 intake plenum, that varies the flow of air inside it with a rotating flap. It’s controlled by the ECM. If you forgot to plug it in, it’s gone dark to the ECM and the code has been set.

I recon the one under the IM is a PITA, [The Injector and Coil Connector]
