HELP! Code: P0304 Cylinder 4 Misfire Dete.

[JvsAltima2005]

Hey everyone! I started my Altima finally after letting it sit for a year and as I was driving it down the road my SES light came on. I kept driving it and the SES light started blinking, so I turned the car around and parked it back in the driveway. I changed the spark plugs and air filter and did an oil change...still the problem is there. I decided to check my coils and noticed that the last coil on the right of the motor, nothing happens when I unplug it. There is also a very strong gas smell coming from my exhaust. Any help would be GREATLY APPRECIATED!

did you check to see if your getting spark from the coil.. it could be a bad plug wire, bad coil, bad distributor. one of those 3 can cause no spark.

If your car was running on 3 cylinders you would definitely be able to tell, it's very rough. But you apparently can't tell?

Happened to me, I had to replace a spark plug boot.
