Car won't idle

Car would start and idle high, because I turn up the idle, but when I turn down the idle the car engine stop. The mixture screw is set ok. No matter what I do, it will start then stop, if I take my foot off the gas pedal. What could be the problem?

Do you
have the same problem?

Clean out the idle air control valve and the EGR valve and see what happens-Also check fuel pressure

Idle air valve is on throttle body and has coolant lines going to it.

It is best NEVER to sdjust idle screw, until you find problem.
