92 Galant Idle Problem

[JT Armstrong]

Could anyone please give me any advice.

Problem is that the other day my 92 Galant (2.0L SOHC) just started dieing
at stop lights and such. It runs fine at high speeds, but refuses to idle.
The problem just kind of came out of nowhere and at the same time the engine
light came on.
I replaced the spark plugs, distributor cap and rotor, and plug wires. Then
I removed and thouroughly cleaned the EGR valve (which seemed to work fine).
I then replaced the oxygen sensor (a real pain). Then I did some web
research and found the engine diagnostic codes (over at
http://www.myzero.com/electrical/code.html) and bought a little buzzer and
got the following codes: 15, then 21 then 25 then 13. Geez! is all that
stuff bad?

15 = Idle speed control motor position sensor (1.8L only)
21 = Engine coolant temperature sensor
25 = Barometric pressure sensor
13 = Intake air temperature sensor

I, of course believe, that it must be the "Idle speed control motor position
sensor" but the codes listed it for 1.8L only and my car has a 2.0L.
I guess my question is just does my car have on of these? Where is it? How
do I recognize it? Any advice on fixing it?

Also, does anyone know a web site or online dealer that has good prices on
mitsubishi parts?

Thanks in advance for any help!

Your cars ECU have lost its memory.
Take off a cable from the battery for 30sek.
Runatt idle for 15 min ,dont tutch the trottle!

Like I said, it won't idle. There's really no way I could run it at idle, or
even get it started, without touching the throttle.

I did do what you suggested already. It seemed that the first code (the idle
sensor one) immediately started beeping. Then after a few minutes the other
3 came back into the sequence.

Thanks for your help though.
