Unknown codes being thrown...
I went on an 800 mile trip last weekend, and my Check Engine light came on twice during the trip. So, I just ran all my codes and here is what I came up with. Note that looking through the lists of codes on here, there are five that didn't show up. Can anyone shed light on these? Also, the only one that I would think might set off the dummy light would be the first one. Anyone know what could cause it? My MAF is currently stock.
Thanks!

the 101 fault sets when the maf and the map sensor values don't mirror each other.are you running a stock air filter or a reuseable type[one that needs to be reoiled?if you run a oiler and serviced recently,you may have sucked oil into the maf.the u codes are all communication codes,almost looks like the battery was disconnected,went dead,etc.i would almost tend to think they have been there since day 1.if not,i would look for a loose battery connection,starter connection,loose/bad ground.
