Asked by Suew0425 Mar 02, 2018 at 07:58 PM about the 1990 Nissan 240SX 2 Dr SE Hatchback

Question type: Maintenance & Repair

Getting really bad mileage. Took out catalytic converter. What could be
causing that?

F_O_R answered 6 years ago

The O2 sensors control the fuel mixture. Without the cat your car will not run correctly. Put the cat back in.

Is there anything I can do? Should I put back in the catalytic converter or new oxygen sensors? Thanks for your help
