I have a 2000 buick regal it has always ran great with no problems today on my way home from work it first felt like a flat tire then I realize it was missing very badly. I was close to an Advance Auto they put it on a Global OBDII scanner the codes it gave me was PO128 - coolant temp below thermostat regulation temp
PO301 cylinder 1 misfire detected
PO137 O2 sensor
Circuit low volts (bank 1 sensor 2)
the guy told me no way had it been running fine with this much wrong. I can assure it has been running fine. What is the first step we need to take to get it running rignt again
thanks

First thing I would do is look at the plugs and wires and pay close attention to the #1 and #4 plugs, wires and coil. I would bet that you have a bad wire. I would get the missed fixed then clear the codes and drive the car and see if any codes return.
