Alright. Narrowed it down to the MAF. For some reason the signal wire is showing 9.5v. With the MAF unplugged it starts, but it idles like shit. I tested the MAF off the car with the 12v FSM test. It gets like 300mv on the signal wire. How the f***? bad MAF?

Signal from MAF should be 0-5v.
Are you sure you have the correct wiring harness/pinout matched?
