koobiidoobii,
I would say that since you have only one code for the oxygen sensor, I would start by checking the particular one and make sure that it is bad first. If it is not bad then I would start trouble shooting else where. Thats where I would start. It won't hurt to clean the MAF sensor but I would suspect the O2 sensor first. If you need to replace it don't buy the generic type that you have to splice in, get an OEM type that just plugs in. Denso or NGK work the best other than a Toyota brand which you will pay too much for.
