I changed my fuel filter the other day. For the longest time I had code 171 and 1131 which were sensors indicating lean. I disconnected the negative terminal when I did my fuel filter and since then the car's fuel economy seems to be really poor. How long does it take to get itself reset? Also, I did the poor man's kkm that same day and I was so impressed I was driving a bit like a mad man really getting on it. Should I un hook the terminal again and drive a little more normal for awhile to get everything back in order again? Car is 99SE v6 MTX
