#3 Cylinder Misfire on idle

[Bidule]

Hi guys I have a Grand Caravan 2005 with the 3.3 engine. I can notice some rough idling especially when transmission in on "D" because RPM is slightly lower than when in neutral. The check engine light is on. I went to the dealer to read the code and he said it was #3 cylinder missfire. Spark plugs were replaced about 1 year ago. I ordered the #3 spark plug wire from Dodge and replaced it myself, still same problem. When i am driving everything is fine, it looks like misfire happens only on idle because of the low RPM. Some day i can't feel any misfires, so i doubt i can be a bad spark plug cause it would do it all the time. Any ideas ? Thank you

Cylindre 3 missfire is P0303 on any car

Start the car, let it idle in park

Take a bottle of spray water add salt in it (half a teaspoon seriously)n spray the wires the plugs and the coil....(coil is at other end of wires).....look for lil sparks.....

he was told by someone ... big differance from KNOWING actual code

went to the dealer to read the code and he said it was #3 cylinder missfire

If the dealer says its p0303 the custumer will say what the **** that means.....mechanik will answer its missfire on cylindre 3.....how is that not clear????
