Had the emissions code for a while now. Maf was replaced. Fuel rich code just came up. Car takes a few seconds to start then turns over. Sometimes I have to give it a little gas to get it to stay running. Bad cat maybe? Please help. Thans!

the p0420 code is the rear 02 sensor, replace it and it'll go away, not sure on the other one
