Back in December my 2006 X5 4.4i displayed "Service Engine Soon" light and went away after I turned it off and on again.
For the past week the "service engine soon" seemed to be coming on and off more frequently. I took the X5 to Autozone for engine check and I was told that there is a misfire for cylinders 5 and 6. The autozone rep told me that the spark plugs cost about $9 each along with changing the boot cable or something similar for about $14 each.
Right now I have 85000 miles on the car and purchased used so not sure if Spark Plugs were changed before. The vehicle is covered with a Maintenance Plan until 2012 but not sure if replacing spark pluges is covered.
