car gave me codes today
PO303
PO304
P1300
tried doing the test on the oxygen sensor and the scan tool would not let me, but a ran the datastreem and it says
O1S1 .50 and the rich light was on
B1S1 14 dont know what # means
O1S2 .87 and the rich light was on
B1S2 14 dont know what # means

dont really know what any of the other numbers mean but i know that the oxygen sensors say its running rich. Dont really know waht to do or whats wrong maybe the timing is off a degree or so i think its at 13 degrees, any ideas????
