I'm pretty sure JSC Speed sells them for around $185. I have the same problem with occassional stalling. I thought it was my FP4R Cams. Sean Ivey swears it's the IAC. If I buy one before you guys do I'll let you know.

 

thnaks let us know ,

 

im pretty sure this thread is going to turn into a big GROUP SALE , lots of people r having issues on their evo that could be iac sensor

 

iac sensor Part Number 1450A069 - Old Part Number MD628318

i noticed that the part that goes in the tb from the iac on my car is plain black ...'

but on a photo i saw the iac has a spring on it , my iac has no spring on it

 

Have the same problem.

 

i've wanted to barrow my friends almost IAC to see if this would fix my problem. Its really annoying especially at the track.

 

I had the same problem I just bought ems and took out my MAF. Thats what worked for me.

 

Yeah, I got lucky and got a used one cheap.
I've seen them on Ebay too.
Make sure after install you disconnect the bettery once to reset.

hi there,
I tried searching but couldn;t see anything. Can you please post a link to the "how to take out your IAC and check it for wear" thread? It would be very helpful
thanks

 

thanks. GotWheelHop will try it

 

even if it has no wear it could still be damaged

 

went to dealership they just adjusted idle screw slightly and idles perfect now 2 second fix had car running tech adjusted screw and it was perfect kudos to south park mitsu
