Chevy S-10 idle control valve ?

I have a 1997 S-10 that will die after starting the engine. It will restart but only run if you continue to give it some gas. Sometimes I start it and the engine revs until finally settling down to what apprears to be normal. It mignt run fine one time and not the next. Just this last week it ran good for a few miles and then died everytime I had to come to a stop. It is not a fuel pump because if it was the truck wouldn't start at all. All the filters are new and it doesn't need a tune up. I've been told it could be the idle control valve and/or an EGR valve that is sticking. Does anyone know where these two parts are and how to change them.Chevy S-10 idle control valve ?
the EGR valve works the pollution control, and is located on a rail on the side of the motor. the idle control is called an AIS (automatic idler sensor) that's located under the carburetor and is connected to a plug that is attached to the throttle body on the carb. chances are its the AIS that's no good any more and should be replaced. take the vehicle to a shop and have them put it on a dionostic equiptment and let them check it.Chevy S-10 idle control valve ?
It is the EGR valve, it is on the top of the intake manifold, driver side. You can remove this, and clean the piston in the valve, BUT, if you are not a MISS Goodwrench, then take to the Chevrolet dealer, and pay for the professionals to replace the valve.
