You need the MAF sensor, don’t try to bypass it, and the air temp sensor does little other than to tell the computer how warm the air going into the engine is so it can make minute fuel trim changes. The MAF is the major player in determining fuel trim, so it needs to stay in the loop. If you are going to add anything to the stock engine, you may need adapters to keep the MAF sensor connected in the proper place.
Is the intake system you want to use designed for this particular application, or are you trying to make it work? A link to the component you are looking at will help determine if it’s feasible or not.
That is the intake I was looking at but the vacuum hose is right after the throttle bodie and if I put that intake on after the MAF sensor then I don’t know what to do with the vacuum line on the aftermarket intake as the stock intake already has the vacuum line on it.
The below link is a picture of the engine(not mine) and to the right of the engine is the intake and you can see the vacuum hose that I previously talked about.
As far as the line goes, you don’t have to use the one on the new intake if the purpose is already resolved by the intake manifold. All that hose is there for is to allow the engine block to circulate air through the PCV valve and back into the intake. You are better off having the non PCV side of the system either being dumped into your air cleaner box or after the throttle body to avoid things from getting mucked up with oil residue.
