was driving home the other day and my car was idling at 3000. out of the blue. so I assumed it was my idle stabilizer acting up.. so I unplugged it and it idles fine now but ive drove it about 3 hours since I unplugged it..... and it just did it again.. but when I gave it alittle gas it went right back down.... help? idk whats going on... or am I just over reacting? hha

What's that? hows it work? what does it test?

try to clean it first

 

its the one he points to first.

 

sweet! thanks alot

 

whatever you do man....once you get it fixed...POST HOW YOU FIXED IT!!!

there are loads of dead end threads, where people have issues, then they never post how they fixed them.

 

copythat.

 

This is the idle valve myself and a few are using.

first time it happened, at a light after a highway run idle stayed at 2,500 to 3,000. turn key off and start car, idle was back to normal. they tend to go bad and mitsubishi charges like $350 for the stupid thing.

 

Yea the air idle control valve and also try clearning your MAF sensor with the CRC MAS air flow cleaner. That tends to get dirty after awhile, now if those two methods haven't worked try looking for vaccum leaks or even the TPS.

 

what should i use to clean it with?
and that amazon link is only to an 05.. mines an 06... will it be ok with that one?

 

got the iac valve cleaned and cleaned my MAF sensor.. thanks for the help guys. ill let you know in a day or two how its running and if i have the same problem looks like yall will have to give me more things to check thanks for the help again.

 

No problem, how's the car running?
