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.

Would a bad Cadillac converter make your van spit and sputter?
The ideal exhaust has no unburned gas in it. Since this hardly happens, a system to clean up air pollution was created. On the exhaust stroke of your engine, unburned fuel is forced out of your cylinder by the piston. That unburned fuel then makes it's way to the catalytic* converter. The catalytic converter basically gets hot to burn your unburned fuel and puts out the combustionally correct gasses. It is possible that your catalytic converter is the reason your van is spit and sputtering, but there are also many other reasons this could occur such as: timing vacuum fuel pressure air spark Signs that it could be your catalytic converter include: abnormally loud converter abnormally shaky converter hope this is somewhat helpful
