1992 Lexus LS400 Intake Issues
 

Having issues that I have been able to isolate to the intake system. I do have two cracked hoses that go into intake system and having trouble finding out whether I can get these hoses pre cut or do i have to buy a roll and cut myself? So far I know for sure the MAF is fine. If i completely take off the air intake system acceleration is fine. Im wondering if it wouldnt be best to just go ahead and put an aftermarket intake system on to see if that helps. Any thoughts on this issue?

What? What do you mean after market intake system? Do you mean putting on a carburetor? What are the issues? Its like anyone that reads what you said needs to guess what is going on.
You said you completely remove the air intake system then acceleration is fine? So you took off the whole plenum, as that is all part of the intake system?
Your post is very confusing. And is why no one will answer it.
