Somethings it says all cylinders, somethings it will only designate one cylinder misfires. Don't know what to do?:

 

Do a cylinder leak down test.

 

pull the coil packs out and see if there is oil on them. if not, pull the spark plugs and check for the same thing. if so, you might need to change out the valve cover gasket as well as the spark plug seal. Also, you might want to change out the spark plugs as well, just to do a thorough job.

 

Do the easiest and least expensive first, put in a new set of spark plugs.
