Not meaning this to be a dumb question, but have you pulled the MAF sensor to make sure it's in the right way, not turned around by chance is it? Second, even if it isn't the problem, you'll want to install a straightener in the tube in front of that MAF. They are super sensitive to turbulence and one is really needed for it to function properly.

I've replaced the MAF and checked to make sure the MAF is oriented in the right direction. I'm going to buy one one of the air foils you're talking about to see if that helps. If it's not that only thing I can try is putting a new gas pedal in the car.

I pulled the intake and valley cover to check for anything and didn't find anything. No cracks or torn gaskets. This is getting ridiculous not being able to idle the car down. I can do it with a carburetor haha. Thanks for everyone's help so far. Hopefully I figure it out soon.

I put the air straightener (honeycomb) in my cold air intake today. I mounted it 1" away from the MAF sensor and it idles every time now. Hangs for about 5 seconds but always comes down. I figure this is because my ECM is not seeing speed so does not know when to idle and when I'm shifting gears. But as long as I come to a red light and it's idling when I stop I'm good with that. It has never done it since I built the car. Hope this helps some other people on here and thanks for all the help!!!
