Ok so these past 3 days I've been running my truck kind of hard. Last night my ses light came on I hooked up my scanner an got codes p0131 and p0151 both said (low voltage) so I cleared the codes and after that I went out it pulled like normal up to about 3k and act like it fell on its face. then if I let off about 1/2 throttle I would pull hard again. So I started driving normal again but I noticed I went from 1/2 tank to 1/8 of a tank in about 40 miles. Would bad O2 sensors cause this problem. It's a 97 silverado with a 5.7 vortec
