Yes, I just had the same problem and I cleaned it with STP throttle body and carb cleaner. Take off the air big air hose off of the throttle body. You will see a small hole on the lower right side. Put the spray nasal on your cleaner can. Stick the plastic nasal directly into the hold and spray it for about 7 seconds. Then take the nasal off of the can and stick it in the hole pushing it in and out for a few minutes. Then put nasal back on the can and spray for another 7 seconds. Now wait for 20 minutes. spray one last time for a few seconds and you are good to go. You will be shocked on how much better you echo will run. I almost spent 225.00 for a new idle control valve, man I sure am glad I did this. My car is running better now then when I first bought it. Good Luck !!

the MAF sensor is between the air filter and throttle body. the idle controll is at the throttle body.
Its located on the throttle body on the left side. Follow the air intake to an intake manifold which sits on top of the throttle body.

Idle is controlled through the on board computer and is not adjustable, however after u cleaned the system you need to disconnect the battery for 5 minutes and then let the system relearn the idle speed, this takes about 30 miles of driving a combination of city and highway.
