I keep getting a missfire in cylinder 6. About a month ago was the first time. I changed the plugs, wires, cap and rotor. Yesterday got same code for missfire. I put some injector cleaner in the tank and cleared the code. Anyone have any ideas why this cylinder misfire code keeps poping up?

 

I had a misfire in my 6th cyl too. chech to see if your plugs are in the right order around the distributor and it also could be that your distributor is turned right around from where it should be. I didnt know it could be but the dealership said mine was and changed it after that it ran better <shrugs>.

 

Could be a cracked head if it keeps poping up.

Change the injector with another one and see if the misfire goes to that cylinder. If it does then that injector is bad, but if the misfire stays on cylinder 6 could be a cracked head [&:] These tend to crack inbetween the valves.
