have lost my idle on a 1995 mitsubishi--what is the problem

A bad idle control module will make it race up to about 3000 r.p.m. when in park.

My 2000 V6 Sonata shakes while at idle also. I discovered I need an oxegen sensor and more importantly an "Idle Air Control Valve". 239.00 is the average and hard to find. .

Because the engine is running. Shut it off or give it gas and it will not idle.

if the vehicle shifts and drives fine. the most probable cause for this is a high idle. most vehicles idle at around 650 to 700 rpms. when warmed up, check or clean the idle air control if idle is high. good-day !

How high is your idle? idle should be 800rpm good oil pressure is obtained at this idle

below the throttle body... once you remove the intake hose, you will see it from the idle electrical plug

The idle speed on your 1995 Cadillac Eldorado can be set by adjusting the fuel pump adjustment screw. Turn the screw to the right to increase the idle speed.

There really isn't an adjustment just the IAC valve which may be dirty causing the idle to be too high or too low so the Idle Air Control valve has to be cleaned or changed.

The idle control valve for your 1995 Nissan Maxima can be found on top of the engine. The idle control valve will be attached to the back of the injector fuel pump.

Try adjusting the idle using the idle screw on the butterfly valve of the air intake. It might be that the idle is just set too high. If that doesn't work, try adjusting the timing. If that still doesn't work, try replacing the Throttle Position Sensor, located right above the throttle body.

Possible cylinder misfire and/or failing engine mounts.

If you have a leak in your vaccum system, it will idle a few hundred more rpm's than normal, the idle speed setting is all electronic and can't be altered.

normally idle around 1000rpm

You don't. The ECU controls the ISC (Idle Speed Control Motor) which adjusts the idle. If idle is out of control (too low or too high) try gently tapping the ISC with a small (0.5 pound) hammer or a large wrench while the engine is running. If tapping the ISC makes a change in idle speed, you need a new ISC. Clean the throttle body whenever replacing the ISC. If the ISC is not the problem, look for vacuum leaks which can cause both high and low idle. Low coolant level can cause high idle. Also, note that many clueless drivers assume that the idle is wrong (high) when the car is just using high idle (normally) for a short time after a cold start especially in cold weather.
