P0132 Heated O2 Sensor Circuit High Voltage (Bank 1, Sensor 1)
when the sensor puts out higher voltage(higher than .4v) then theres higher oxygen and in this case may be caused by the misfire possibly.

ok did you use dielectric grease? sounds like a coil gone bad. you can get them on ebay. i'd pull the plugs as well to see which one it may have been and then torque them down to 30ftlbs to prevent any blowouts and then put the new coils in.
