95 2.2 idles low??

when i start it cold it idles up to 1400rpm then it drops as it warms up down to 400rpm hot.
and while driving when i come to a full stop its at 1100rpm (its an automatic) sometimes, mostly in the 400rpm range. once in a while it will hang about 900rpm.
any ideas? the car sat for 14 months before i got it.

I think you have a couple extra zeros in that post my friend. I'd say the 900 rpm sounds right, but 400 is pretty low. IAC control maybe?

the iac is a device that looks like the wiper motor but just a little smaller.

It should be located on top of the throttle body.

The iac controls the idle in your car.

so that has to be your problem.

Are you sure it's 400 RPM. I don't even think the tach goes that low. The first mark on my 2.5L is 500 RPM and my car idles around 600 RPM when hot.

Besides, what's wrong with a 400 RPM idle, uses less gas.

yea 400 rpm it was on the pin
it wont stall but it comes off the line slower and i get some belt sqeeling
the average idle speed for any car should be about 900rpm with the engine warmed up
sounds like your cars off a little

I also have the same problem on my 98 outback sport. Sometimes when I drive it, the idle will drop to 2-400RPM at stops. It has never died, and the problem seems to come and go... I'm stumped

I should have mentioned that I have a MT, and it probably really idles around 650 - 700 RPM, but I've never had any problems with it at all.

I don't think there should be any belt squealing at any speed. Do you happen to know which belt it is? Could be too loose or too tight? I know sometimes overtightened stuff causes more friction but I've never heard of this in a car.

idles back to normal dont know what happend maby somethin was gunked up. car sat for about 14months before i got it.
just in time for inspection last day for my temp. registration. idle is about 600-650 that works for me. from what ive read you have to adjust the idle with the ecm.
