I have a 2001 Ford Explorer Sport with about 130k miles. About three months ago it started running very sluggish and at times even backfires. I ran the codes on it after the check engine light came on and got P0102, P0172, and P0175. Basically the engine is running rich on both banks and it's sensing a MAF low sensor fault. I have changed the MAF, all spark plugs, and the idle air control valve. It's killing my gas mileage and causing terrible acceleration. Please can anyone help me out here - I'm stumped. Could it be a clogged catalytic convertor?
