Mitsubishi: Mirage surging at idle

I had a small problem with a sticking auto choke on my magna, re set it and
problem went away. Maybe your having the same problem.

The Idle Air Control (IAC) motor is being adjusted up and down by the ECU.
This can be caused by several things.

a) a build up of oil carbon and fuel gum in the throttle body. There are
products you can spray into the throttle body to clean this out. Have you
ever replaced the air filter?

b) the idle speed valve may need to be adjusted. There's a 10mm plastic
cover on the top rear (or front, I forget) of the throttle body. Under this
is a big Philips screw. This adjusts the idle speed. If its screwed all the
way in, screw it out a bit. Otherwise, screw it in a bit. Also see a)

c) you have a vacuum hose leak somewhere.

d) check all the electrical connections around the throttle body.

Finally, disconnect the battery for 30 sec to reset the ECU.
