Misfire
I was driving my car this weekend and it was raining very hard. Car was running fine and well, then i drove through a very large puddle at slow speeds and the whole car was practically engulfed in water. About a minute later the engine started to misfire real bad. I managed to get it home, and the next day the car would idle fine and i could rev it up but when I put it in gear and try to drive the motor misfires horribly, I can hardly make it up my driveway. I don't know if I should just replace the spark plug wires or if there is a bigger problem. What do you guys think?

Well, I had time to work on the car this weekend. I pulled the o2 sensor and put on an old one i had lying around, and the misfire stopped for about thirty minutes, then it threw a P0306 and P1153. This was the first time it named a cylinder w/ a misfire so I pulled the wire and the plug. Both looked fine, so I went and bought a new o2 sensor. After i put it on I drove around for about 25 minutes and it ran awesome, even better than before it started missing. Then it sat for about an hour, then when I started it to come back to school it seemed like it was missing slightly in first and second as i was leaving a neighborhood but the engine light didn't come on or anything and after i got on the main road it was fine. I drove it for about 50 miles to school and it ran fine in 5 and 6 gear. Does anyone know why it would be misfiring after the new o2 sensor was on and not throw any codes?

So.. I put in new o2s about two weeks ago and now the car is misfiring again. It will usually not throw any codes but today I got the 1153 again, does anyone know what i should do?
