    If I remember correctly it should be behind the throttle body and in front of the distributor on the intake manifold.

Located on intanke manifold. What are you doing?

Typically. there is a build up in the exhaust cross over port that is centered front to back and passes directly under the choke and carb. Be sure the valve at the end of the right (usually) exhaust manifold, is free and working.

The EGR valve is subject to problems from exhaust particles, that sometimes jamb it open.

The EGR is located under the intake plenum just about between the #4, #, #5 and #6 intake runners . It is real difficult to get to. You have to remove all the upper intake runners and if you do be sure get new gaskets as the old one's will rip or leak. The bolts sgould be torqued as well.

1985 corvette, 64,000 miles. idles rough and sounds like it wants to die but doesn't; can watch rpm drop and come back. Just changed the egr valve too. What should I try next or look into?

Your problem can have multiple sources. Spark plugs, change those if they are old. Injectors can be dirty. There are injector cleaning products that you can try. The best I have seen is one that you inject the cleaning solution into the system via shrader valve at the fuel rail, disable the fuel pump and run the car only with the cleaning solution that is coming from a pressurized container.
At the same time change your fuel filter. If your distributor rotor cap and spark plug wires are old, replace those. There is an idle control air valve that regulates your idle. That could be a source of the problem also. Query the on board computer and see if you have any codes. My advice, start with the spark plugs, wires, distributor cap and fuel filter if they are old and go from there. That should be an easy task that does not demand a lot of skills. See if that helps.

My 1985 corvette smokes out the exaust only when at idle and engine at running temperature.

most likely worn valve guides and probably dry cracked and fallen off valve stem seals you may get lucky with just replacing valve stem seals but may need guides installed in heads

1986 corvette running rich at idle, give it gas and stubles really bad max speed about 30mph won't pull hills (dies). replace fuel pump, fuel filter, tps, egr valve, temp sensor, o2 sensor,

have you tried checking the map sensor this can sometimes cause the engine to run oddly. also check for good spark check wires when its pitch black out check for wire arching. also check fuel pressure with a pressure guage.make sure cap and rotor are clean of deposits. keep searching and you will find the weak link.

How do you change the car battery?

In my 1985 corvette the battery is located under the hood, but you must remove the panel on the driver's side to gain access to the battery. Hope this helps
