Today I pulled the trigger and bought myself a 2001 bmw 330ci silver/black manual for 4.2k with 120k miles. It has misfires on cyl 4 and 5. I will using the great guide written on this board for help. I suspecting ccv, intake boot or vacuum hoses causing the misfires. Bank 2 is in open-fault mode the entire time. The car does idle fine and drives fine. Here is a crappy picture for now and I will be updating as I discover, fix issues. I look forward to writting DIY's too.
