Default E46 m3 vanos removal need help setting timing chain

Hi,
I am new to the site but have read alot of good info here.
I just did a valve adjustment on my 2002 e46 m3, decided to change the sprocket bolts behind the vanos that people have had come loose, and put on a timing chain tensioner. Got the car back together and now it has a rough idle and tries to stall. Got misfire codes and vanos codes 184 and 185 ( i believe those are the correct codes). Cleared the codes and changed the plugs but still rough idle. Raj at beisan says the car is out of time since the gears were removed from the sprockets and that is the reason for all the codes. The car was running fine just annoying ticking due to valves needing to be adjusted. The car is much much quieter but trembling at idle. How can I go back at check the timing without special tools?

you really should not change out the cam bolts without the timing tool. Your timing is most likely off when you put it back together.

....id suggest leaving something like that to the professionals...theres no real way to "tell" you how to retime the motor without having the special tools required to do so..
