1994 Plymouth mileage: 140,000. This van has been having problems off and on for approximately 6 months. The carburetor is flooding but the engine is not stalling. It has low power and is guzzling gas. Extremely low gas mileage. A service person said it was the catalytic converter; it was replaced and hasn't cured the problem. It is running better but not right. Also is there another catalytic converter inside the manifold. Also tried a new oxygen sensor but couldn't find it to replace. The engine is a Mitsubishi 2.6 liter what else could it be. Thanks

If your carburetor is flooding it probably is caused by a failing needle and seat inside the carburetor or a bad float. Also, check for a vacuum leak. The catalytic converters fail if the carburetor is running to rich due to the extra fuel. Fixing the carburetor-flooding problem should be done before replacing any of the catalytic converters. We have not worked on your model car for a long time so we are not sure, but believe that there is “pre-cat” in the manifold. If there is, it will be obvious because of the large bulge in the manifold.
