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..

people from utah sure love parking their trucks ontop of stuff.
you sure its a 24?

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.

Also, could you please explain to me on how to check the wiring and maf? I looked on google for forever but didn't find anything.

You're not going to find a lot of accurate info if you search MAF... No Supra ever used a MAF.

I forgot to mention I have a safc2.


I'll look it up to. Do you have any idea on my problem? also how would I go about testing the wires to the sensor? It seems like every post I find on here your a very big help to them! Thanks.
:dunno:

I think I already have the Lexus afm housing?
