Do you have all three grounds securely bolted to the coil?
You can see the three different eyelets in this picture on the right stud:

One of those grounds is a braded ground strap that bolts to the driver side of the chassis.

I cant really see, can you take a picture of the grounds if you have the chance? I dont recall seeing a braided ground strap also.

I just replaced the grounds and still the same volt reading from the harness.
Is this coil good? Im stumped here guys. ICM checks out good, Im gonna replace the IAC valve tomorrow (spare one laying around)
Is there anything I missed thats giving the low volt reading to the Opti?

So, your jumping over to test out the ICM harness when the previous advice was to check the opti harness (you would check the opti harness by disconecting it at both ends and use the meter to check continuity of the wires- "ohm it out" as people might say).
People often get confused on the ICM terminal test results, because the wiring diagram does not show the terminals A-B-C-D like they are on the physical plug (they end up putting their meter on the wrong leads).
If you are getting a code 36, it's most always going to be either the opti or the connection to it.
