I am receiving a P0131, P0300, and a P171. I replaced the Bank 1 Sensor 1 O2 sensor on 6/21/2013. I cleared all codes but by the next day the MIL was on and the same codes are back. I have also replaced the MAF sensor and put a bottle of GM fuel treatment through my system on two different tanks of gas. I am out of ideas and I was wondering if I would receive these codes for bad intake manifold gaskets? Or are there other reasons for these codes? I appreciate the help.
have the same problem?
