Has anyone bought this new IAC?
I've installed it and it's experiencing fairly high idle. It's averaging 1500rpm, sometimes it'll jump to 2000rpm.
I know that the ECU is suppose to relearn the idle, but is it supposed to take a while?

It's occasionally jumping around too.

 

That's normal. You need to find the person with evo scan to adjust that.i bought that part from ebay,installed it and went to the tuner.but I drove with high idle like for a couple of weeks lol.

 

Try disconnecting and re-connecting the battery, see if that changes anything.

 

Yeah I've done that a few time's already

 

That sensor does not look like an OEM part, it looks aftermarket. I would purchase a factory IAC sensor from Mitsubishi and install it, then re-evaluate and verify the repair.

 

the factory sensors are like 400 bucks, you can find the same one made from another company for 21.95 on ebay, are they the same? yes, companies out source other companies to make their oem parts all the time,

 

it takes a while for it to adjust the idle but if it doesnt after a few hours of driving. I would adjust that little slider thing on the throttle body.

 

It's been a few days now

 

The sensor is exactly the same? Same part number and everything? I've had plenty of troubles fixing cars with cheap sensors, only to find out that a new OEM sensor fixes the issue. You should not need to adjust the screw on your throttle body, in order to cover the real issue.

 

There is a biss screw you can adjust on top of throttle body. You will need a stubby Phillips screw driver. Need to have vehicle running when you do it and you can slowly hear the idle drop. I had to do mine a few weeks ago.

 

Let me know if you need a OEM iac I got one laying around
