ive been messin with this car for two days, tried another used maf and nothing. doesnt even change when unplugged. if anyone has any ideas thatd be great, thanks in advanced!

ive checked and found all vacuum leaks no boost leaks no intake leaks.

the video is holding the throttle about 1/4 down. any more and it just floods like crazy and backfires and pops out of the intake.

I haven't actually done a "boost leak test" but I've closely looked at all of the piping. Also if I unhook the bov it blows boost out no problem so i know its getting boost..

I'm guessing you went through the Photobucket. Hahaha

I believe it was intake air temp sensor and maf.

yea i checked your photos out.. I want a rabbit man. those suckers are peppy..

I only have a couple of suggestions. as for code 24.. I don't know man.
but im experiencing the AFM code also. what I did was go out and get one from a junk yard off of a lexus ls 400. the electronics are interchangeable.
that solved my problem but it recently came back.. so I went back and bought the clip and wires for it too. Just got it today and haven't put it on yet. So besides that suggestion I would also consider instead of replacing the afm and wires to test it and see exactly which pin is causing the problem. then replace as necessary

I just got it sat in a garage for 15 years.

I went and looked in every junk yard for one and couldn't find one. I tore apart the harness and looked for bad wires and didn't find jack.
I added a new ground from head to the body just incase, i reset the battery and started it a few times to get it to idel, I noticed that it won't rev up at all until the engine light comes on. After the light comes on it does what is in the first vid. I'm posting a second one of what it does till the light kicks on.
