Unhappy Evo won't idle at all.

Hello my 04 Evo won't idle at all. I replaced the iac and still nothing. I've seen that changing the egr solenoid valve would work. Any thoughts do have cams but car was fine couple days ago.

Mods? Tuned? Do you happen to have a wideband installed to know if it's stalling due to being lean or rich? Do you smell gas?
Have you checked all your vacuum lines?
Can you hear noise from the fuel pump?
What do the plugs look like?
Has the BISS been messed with?

There are soooooooooo many reasons this could be happening. Be patient.. it may take a while to guess the right one.

Full bolt on's nothing to special. I'm gonna do a boost leak test to see if anything is leaking. I'm not patient just wanna drive her around.

I don't really know where to adjust it since I don't have evoscan.

You're gonna have to get a computer with evoscan to park the IACV before you adjust the BISS. Then try starting it again.
