Honda Civic CX 97 1.6L - Diagnostic Code help
 

P0141 - O2 Sensor Heater Circuit Bank 1 Sensor 2
P0700 - Transmission Control System (MIL Request)
P0715 - Input Turbine Speed Sensor "A" Circuit
P0301 - Cylinder 1 Misfire Detected
P0302 - Cylinder 2 Misfire Detected
P0303 - Cylinder 3 Misfire Detected
P1300 - Unknown Diagnostic Trouble Code

Hi guys,

So far spark plugs have been replaced, catalytic converter, and distributor.

We need some help on the following codes.
P0141 - Is that the second sensor under the car?
P0700 - Anyone have any known fixes? or is this just from the misfires?
P0715 - Any other possible issues besides replacing the Speed Sensor?
P0301 - Clicking and gave 13.0 Ohm reading
P0302 - Clicking and gave 12.8 Ohm reading
P0303 - Clicking and gave 12.8 Ohm reading
Also, Cylinder 4 gave a 13.0 Ohm reading, if I'm reading this the correct way... starting from the injector nearest to driver side then across.

P1300 - Not sure what this is.

Car drove fine before the spark plug change, it now overheats. No transmission slips. Speedometer is not working.

Any help would be great!

Thanks!
