i have an 02 jeep wranger and i got the status codes 302 and 456, ive changed all the spark plugs and reset the status codes and im still getting a misfire on cylinder 2, but the 456 went away.
driving also feels a little rough, ive heard i could have bad gas, and that be a cause.
it also went a little while without being driven, 1- 2 months.
any help as to what i could do/ try?

Ive been told to change/ replace the wires but on my engine there are no wires or distributor cap,
theres just some sort of block that runs across all of them.
there are additive in it now but i will try getting rid of all the fuel in it now then ill use fuel injector i guess
 
sounds like you have a sensor messing with you and the fuel you using can do it too. and when is the last time you ran injector cleaner? a dirty injector can cause a miss fire. are you using fuel with alcohol in it. it can cause the 02 sensor to miss read and make the fuel to rich.
