Here is a video of the car idling with the MAF disconnected. I have a ticking noise that I am not sure what could be the issue. One of the rocker arms was loose and didnt have a shim under the lash adjuster. When I put the lash adjuster under it the rocker arm was taught like it should be and not loose. I should of checked the other but I thought that was it. I am going to check when I can and put shims under the ones that are loose.

Have you tried cleaning the MAF to have it idle better? I had the same issue with my Mach, and it cleared it up.
