keep getting this random misfire code. cylinder #2 has an excessive amount of gas going in it . the spark plug was covered in gas. it runs really rough in gear and i get a CEL and when driven the CEL fllashes so i have not driven it since. but i cant figure out what the problem is.

that will most likely indicate a bad injector, and will need replacement

it turned out to be a bad coil and a defective sparkplug wire. but now the car is overheating. i have only had this car 3 weeks and i have replaced plugs, wires, 1 coil ,changed oil ,and flushed and filled radiator and put in a new thermostat. checked the fans and they work on a 12 volt source . could it be one of the relays cause one of the was replaced right before i bought the car. i am kind of stumped. never had so many things go wrong all at once.

well ,if the fans work. and one of the fans come on when the a/c is turned on(it is supposed to) then either the relay to the radiator fan is not good, or the engine coolant temp sensor is not good, either or
