A faulty injector will cause this, you can get them sonically cleaned and flow tested it may be a good idea to have them serviced as the mileage is up there now.The money saved on fuel will pay for the job in no time.

Oil in cylinder -Recheck the compression on no.5 I could be wrong on the compression specs-if it is use a decarbonizer-the reason I've mention carbon is your mileage
