Default Couple of codes: P0101 and P0135/0155

So the SES light came on last week and I scanned the codes, getting the results of P0101 and P0135 and P0155. I know the last two are O2 sensors so I'm not too worried about that, but the first one has to do with the MAF. Anyone have the same code and fix it? You guys think I should just try to clean the sensor or am I going to need a MAF or what? I cleared the codes and they were off for like a day and then came back on.

I'd check the ENG SEN fuse first, unless you can scan
and see MAF frequency and O2 switching behavior to
put a finer point on it.

Ok since I had the problem right before I put it away in storage I didn't check anything until this week after I got the exhaust finished the the ABS fixed. The fuse diagnostic tool said the ENG SENS fuse was good so thats not the problem, I also checked the MAF to see if it was dirty and cleaned my K&N filter and still have the SES light on, so is my MAF most likely bad? If that is the case is it going to hurt it to run it like is for a couple months or is it something that I should replace soon?

Probably the worst that could happen is fouled plugs and/or O2s. Your best bet is to find someone with a scan tool and some know how.

Its been scanned but I guess I could take it to the guy that tunes my car. I've got a friend that I can pick a used one up for so I'll probably just do that. I guess that could be the reason I'm getting O2 codes too? Cause I've got the rear O2's tuned out.

So far I've installed a used MAF that I bought from a friend of mine and cleared the codes and they didn't come back on after starting the car a couple times and a 3 hr road trip back down to school. Hopefully it has solved the problem.
