I have a 2001 330ci. I have replaced the vanos, all the hoses, spark splugs, and the DISA. Prior to replacing the DISA the car did not shake as bad. It was able to stay on and for the most part function. My mechanic has stated that the DISA needed to be replaced so i went ahead and did so. From that point on the car is really rough. The peake codes I get are F3, EF and F1 which are misfiring for cylinders 2,4, and 6. I went ahead and purchased the coils and no change what so ever. I ensured that I reconnected all the sensors I unplugged when installing the DISA ( MAF and DISA). I have searched online extensively and can't seem to find a solution. Can someone please provide me with any feedback. Am I missing something?

Thanks in advance,
