Evo won't idle at all
Hello I have a 04 Evo that won't idle at all. I replaced the iac still didn't fix the problem. Anything I should try I heard changing the egr solenoid valve would work. Desperate need for help.

Probably a MAF sensor. when mine went bad, i had all sorts of idle and drivability issues. i changed spark plugs, Cam pos sensor, fuel pump, MAP sensor and then, it was a bad MAF. it wont throw a code unless it is completely gone. let us know!

Maf is a possibility.
Also a large leak after the maf. Aka un meterered air.
Huge vaccum leak
Big leak on any pipe after the mass air flow.
Have you done boost leak test?
Is car tuned?

Just asking cause sometimes if the battery is removed it will switch maps so you might have switched to the 91 map or vyse versa. Happens to me all the time.

Scan for codes.
Determine whether its lean stumble or over rich stumble. With current data from 02 sensors or a wideband.
Did it happen all of a sudden? Or did u work on the car then it happened? Etc etc. Need more info
