Worked on the supra for a bit this afternoon and found that the TB is sucking air. Its right between the intake and the TB. I pulled it off and plan on putting a new gasket tommorrow. If only this is going to be my problem.

I just took it for granted that you didn't have any vacuum leaks.

A vacuum leak after the MAF will cause a check engine light (for the MAF) and will also cause a lean condition which will cause that pinging sound you hear.

I think the TB gasket will fix your problem.

I did to until I could hear a small hiss under the hood. So I broke out the starting fluid and started spraying around where everywhere something meets up. And sure enough, I spray it around the TB and the car tries to die. So bingo, found a vacuum leak. I should know this afternoon whether or not it does fix it. Right now it seems to start and idle fine, a little hesitant when you give it gas but will not rev past 2500rpm. Its like its hitting the fuel cutoff. But I wonder why it would run fine for a whole day then i wash under the hood and it all of a sudden gets a vacuum leak. Its crazy!

I also took the cat off and gutted it. So maybe that will help a bit. I also plan on swapping out the fuel filter today to.
