Evo 8 trouble starting
hey guys! I have a 2003 Evo 8. Recently it started not reaching full boost (super laggy and peaked at 17-18 instead of 22). Then trouble idling, and wanted to die when coming to a stop. Blip the throttle, rpm’s would drop and die. Started looking at all the vacuum lines and found one vacuum line disconnected from the EGR valve. Connected it back, started her up, and idled perfect....for like 5 second. Died again, but have not been able to start it at all since. Just a couple of days. Turns over fine tho. Checked every single vacuum line, all are ok. Checked any electrical connections (I.e. solenoids and such), they’re good. No burnt fuses.
Engine throwing codes P0107 and P0113.
P0107 is for the MAP sensor. Took it off and cleaned it well. Nothing.
P0113 is for the IAT sensor. But from what I’ve read, this simply will throw a code, but not have any real symptoms. So kind of at loss guys.
I know there are many experienced members on this forum, so any advice/suggestions would be greatly appreciated. Thanks so much in advance!

if that’s the case, and both codes are thrown, could that mean that the sensor is dead?
Also, I saw a video with an Evo owner cleaning his, but unlike his sensor, mine has a black plastic tip with a small hole with an o-ring that plugs into the IM. His was just open. Can this tip be removed to clean it better? It didn’t seem to want to budge, and I didn’t want to force it and break it.

I had this happen to me, it was my IAC ( sensor on the trottle body) starting to go out. It control the amount of air going inside the engine while the motor is running. There is a test on youtube. I used the camera on my phone to record to see if the actuator was moving all the way and it was not. Hope this help

So I did the iacv text, and it seems to be working properly. So I’m at a loss. I have a code thrown for my IAC sensor...what do you guys think? Could my IACV still be faulty, or possibly just the IAC sensor that needs to be replaced? Just want another opinion before I start ordering parts. Lol I’m thinking it’ll be something related to it tho. thanks guys.

by affecting idle would this mean turning off at a stop sign or turning off while changing gears on a turn? I kinda need help because my evo has been acting up by turning off at random times while driving but it always starts up.

How did you check your vacuum lines?
I would say this is vacuum leak.
Perform full vacuum leak test from turbo.
Goodluck
