You are going to need more than a simple scan tool. Get one, or take your car to someone who has a scan tool that can give live misfire activity.
Another alternative is to get a COP probe that can detect firing / misfiring. Once you have confirmed that a certain cylinder(s) is misfiring (and all the others good), then you can start looking for the cause. At that point, you can swap a coilpack with another cylinder, and see if the problem moves. I'd also take a look in the spark plug bore to see if there's oil present. If enough oil leaks from the valve cover center gasket, that can cause a misfire. Check and clean all the grounds.Pull the plug from the missfiring cylinder and see if it's fouled...if it's not a light grey, put in a new plug.

Thanks!
I have a friend who has a "real" computer. I'll take it too him and see what his computer tells me. I have replaced all 8 spark plugs as well, there was a little oil lying around but certainly not enough to cause this. Used Bosch plugs. Anyone else ever have this combination of codes?

Think I found the problem
Hi guys, think I may have found my misfire problem. I hear a vacuum leak at the back of the engine. When engine put under load, brakes on in drive giving a little gas, There is a definate hiss from the rear of the engine compartment. CCV most likely culprit. Under the same test it develops high vacuum at the oil filler cap. Ordered a new CCV plate, Fingers crossed.

Well that did'nt work
Hi guys. Update on my missfire problem. Had to remove upper intake on this X5 4.4 in order to replace the CCV plate. There was a metal coolant tub blocking some of the screws. I also found a small vacuum hose about 12'' long deteriorated behind the pass head. Replaced ccv, hose, intake gaskets. That's a job and a half guys. Well guess what? My problem persists! Again, at high rpm, I'm getting flashing CEL and still three misfire codes. Ready to drive this F#c^er off a cliff. My suspicions of a clogged cat will have to be further investigated. All that work and $170 worth of parts later. Thats one weekend I'll never get back.

Is the engine on your car the N62 engine? Could be the intermediate levers on the engine needs to be replaced. How much miles do you have on your X?
