No, the catalytic converter is downstream from the EGR valve so it has no effect on it.

Will a bad catalytic converter burn gas?

Yes, a faulty catalytic converter can cause fuel consumption to raise. Replacing a known bad catalytic converter will help, but keep in mind, the catalytic converter usually does not fail on its own. converters are pretty tough, living their lives running at 2000+ degrese internally. I would check your EGR valve and EGR valve tube for blockage or carbon build up. a faulty or clogged EGR valve will overtime distroy a catalytic converter. second thing to check is your Oxygen Sensors. these sensors are the computers first reading of bad fuel mixture, if they are clogged with carbon, they can distroy your EGR valve, which inturn kills your converter.
