I have a '91 L98 w/ 84k that I recently changed the ignition module, cap, rotor, wires, plugs, with no engine codes and the thing is still running very rich.. can smell it. It has also recently stalled a few times on me and I cannot start it until I let it sit for a few minutes, almost like it's flooded. The idle also fluctuates frequently between
800-1000 rpms at idle. Someone had suggested a new EGR valve. Any suggestions would be appreciated. Thanks.Eric
