Egr valve wanted to find a picture of an egr valve and where it is on my 1998 chevy s10 blazer 4x4 4.3 all help greatly appreciated. thanks

you're correct the 98's come with an EGR valve and the 99's don't.

try cheaking egr valve

the egr valve is located on the drivers side next to the fuel rail. here is a picture of the valve

the one possible problem is the egr valve. If your blazer has the Vortec 4.3, the valve is located on the front of the intake manifold. You must remove the intake rubber boot on the throttle body to see it better. It's very possible that there is chunks of carbon holding the valve open. I recommend cleaning the egr valve ( carb. cleaner works great ) and replacing the Egr gasket with a screened gasket. This will take care of it stalling and surging.

sounds like the starter is bad

How is it running before it quits onyou. This could be the culprit of an egr valve. How many miles on thevehicle. The egr seems to die on a certain mileage pattern. Also youcould start by cleaning the egr valve before replacing it. This couldvery well help the situation, but this is just a guess. Hope thishelps!!

It is beneath the air intake connected to the upper intake, that's probably why you can't see it. The manufacturers don't make things easy.

Hello;
Make sure the distributor wires are hooked up and making a goodconnection at the base of the distributor. Also make sure the coil wire is fully in the socket. Make sure no wires got pinched for the relays. Hope this helps;
Thanks;
