A little back ground on the probable cause.I took out the intake and removed the egr and charcol can, the other egr valve, the secondary butterflys.I should only have vacuum to brake booster, fpr, TB, iacv, and i dont know remember what else? am i missing something?

after putting the car back together it wouldnt idle, so i unplugged the MAF- bam it holds a 1500rpm idle.

I tried a friends MAF from his s13, still won't hold an idle.

It's raining so I can't check the TPS. The Iacv is plugged in, and I can't seem to find where I went wrong putting everything back together..

someone guide me as to what I could've left unplugged, With everything back together I can't see much of anything connected to the intake..

Hmm. You'll probably need to plug up the hardlines under the TB. Most of them go to the canister which you have removed. I had the same thing with my car although i still have the canister.

No vacuum leaks after repair was done? Maybe a pinched intake gasket?

That might be the case, and I believe my IACV may have taken a crap too, that might be why it won't idle
