You`re probably experiencing the results of failed VANOS seals (assuming yours havent` been replaced recently). IIRC, `99 was the transition year when they changed over from single VANOS to double, so you`ll have to check your production date. Double VANOS is actually the easier one to repair. It`s a bit time-consuming (4 to 6 hours is typical), and requires attention to detail, but it comes with excellent instructions, and IS doable for the typical shadetree mechanic.

Call Rajaie at Beisan Systems (they manufacture the seal kits) if you have any doubts or questions.

Multiple misfires can be caused by clogged cats. If yours are original, they are suspect.

VANOS seals are a must, in any event.

Thanks VANOS seals were done 18 Months ago, BMW mechanic suggested driving it for ahwile to blow out the O2 sensors as they may be dirty? Doesn't sound right, but I just got back from a weekend trip and drove over 500 miles and still get the same fault codes

Definitely air intake leak.
Check lower intake boot elbow and all connection to the throttle body.
