Misfire can be caused by many different types of problems with your valves. It could be burned or leaking valves, carbon build up on the valves, weak or broken valve springs, worn valve guides or lifters, broken worn or bent rocker arms or pushrods, worn camshafts, improper valve timing, or worn pistons or rings. A misfire is basically when the cylinder is not producing enough air-fuel mixture properly, so your valves may not be supplying the proper amount of air into the cylinder, for the compression to be strong enough for combustion. Faulty: plug, plug wire, ignition coil, ignition module, fuel injector are the most common. Coolant leaking into a cylinder is another. Internal engine problems such as burnt valve, broken valve spring, bent push rod, worn rings.....
Cylinder # 2 misfire. See related questions below.
try checking your 02 sensors
P0304 is #4 cylinder misfire. P0131 is O2 Sensor Low Voltage Bank 1 sensor 2

the p0420 is a bad catalytic convertor, downstream oxygen sensor is switching too fast which causes code to set. p0300 is a random cylinder misfire. p0304 is cylinder #4 misfire, p0307 is cylinder #7 misfire etc. misfire codes are probably due to bad secondary ignition i.e. plugs, wires, cap, & rotor if it is not distributorless ignition. secondary ignition problems will also damage catalytic convertor quickly. (cat. will get too much cat food or fuel) DO NOT waste your money replacing downstream 02 sensor, it is working or else vehicle COULD NOT set this code!
three
NO it will not.
ignition coil
195 degrees
it located right in back of the tranmission.
where is the 02 censor located
