my toy-ota

Hi, my name is josh and i just got a 94 toyota SR5 with the 3.0L 6 cyl. I've had it for about a month now and noticed that every time i drive it, it marks the oil pressure really low, even though I check it and its full. Also, it has really bad gas mileage compared to two other similar trucks i know of. I did a complete tune up on it including the gas filter, and it still runs the same. About three days ago the check engine light went on and i had it diagnosed, it gave me three codes: 42,43,and 71. Can anyone out there give me some tips on what is wrong with my truck and how to fix it? I would appreciate it.
