: Help with reoccuring misfire in cylinder 6 ... ???

04-24-13, 11:07 AM

Wanted to know if this has happened to anyone else.

About 3 months ago I had all my spark plugs changed and the coil for cylinder 6 replaced. Car was driving great again.

My cars been sluggish the last week or so and yesterday my CEL came on driving uphill. Code reads misfire in cylinder 6.

Is it possible this is a different problem like the actual cylinder and not the coil?

Any help is appreciated.

Is the plug oil fouled?

No, Its not.

The mechanic is replacing the coil for me this afternoon but I'm assuming there's got to be something cause the coil to go bad this fast.

I know the v6 like the n* is cop but perhaps the boot and spring is failed. Replace them.
