well, i did what that guy at toyota recommended.
I cut the vacuum chamber off of the bottom part of the stock air box- pretty sure it was the bottom half..
It has two ports for hoses to connect.
I used a bench grinder to get all the edges smooth.
I had to do this in order to get it to fit where i did:
(to the left of the "engine coolant" thing- pink juice and under the black box also to the left of the pink juice. the black box has hoses going into it further left. I used electrical tape to hold the new vacuum chamber up to the black box. everythings covered by engine plastics, so it doesn't look ghetto.)
From right to left there is now a hose (the AEM
manual said to ignore), a check valve (one way air flow), a hose, the new vacuum chamber, a hose to the left side.
I got the extra hose(small one) from the stock airbox. It was connected to some sort of butterfly valve that closed when i put vacuum(sucked on) the hose. I believe this is the valve the ECU said was stuck closed with code P2441 at autozone.
Well after finishing everything, I went to the gas station for gas and so the engine could warm up for lift. I took it to the interstate and it seems to have worked. Staying in lift going from 3rd to 4th was easy, but I'm not totally sure when lift kicks in now.
I will continue to test things out and let you guys know what it's doing.
