    What does it mean when your car has a very low idle at 500rpms and how can you fix it? when you start it, its fine, the idle sits at about 1500rpms and you have a lot of free play.. but then driving it down the street, it goes down to 500rpms and is very easy to stall it if you dont give it gas quick enough or not paying attention. its a 90 integra.

    The idle screw doesn't just more by itself. :) The IACV will normally make it idle high. Change the plugs first.

    The IACV adjusts idle under load though, so it shouldn't be a factor if you're just in neutral. Do plugs and shit first, probably your best bet. If not, i'd adjust idle screw... might be masking a problem, but i mean, its a 90 integra.

    My old Mazda MX-6 did something similar. As long as you were on the gas it was fine. But as soon as you pushed in the clutch the engine would want to die. The car's computer would try to keep it from dying and it would go through this series of high-revs and low-revs, but in the end it would die. Turned out to be a cracked air plenum. The car didn't have a vacuum to pull the intake air in when it needed it and and the engine would eventually stall. The reason it worked under load was because it was sucking in enough air to pull a small vacuum in the plenum and get the air into the cylinders.

    So, cliffs:
    check the black accordion (sp) thing on top of the engine for any cracks. It's cheaper than spark plugs.

    Damn, that sentence is hard to read.

    Why do you want your car revving so much at idle? It just wastes gas and is harder on the engine (slightly).

    Do you have a MAP sensor? Try tapping on it with a rubber screwdriver..

    My S2000 would dip to 200-300 RPMs and it'd shake like its about to stall...I tapped on my MAP sensor a few times and it fixed it.

    clean your idle control valve. It's right at the entrance of the throttle body.

    I've had a bunch of older jap/american cars that experienced this same issue and this was the fix for all of them.

    Remove the hose from under it to let the dirt/fluid drain.
