If anyone is following...
I changed the coil packs/plugs in 7and 8. Started it up, the check engine light was OFF
Still idled rough and had drive train malfunction light on. I tried using the OBD scanner I purchased, but it wouldn't connect to Bimmerlink a be second time. While messing with this, I noticed the drive train malfunction light stopped coming on when ignition was turned on. Idle seemed to smooth out a little.
I great drive it about 3 miles and it ran GREAT. No CEL or any other light. I stopped, turned it off, let it sure for 1 minute. Started it, CEL and drivetrain malfunction lights were on and I didn't think I would make it home, it was running so rough. I'm ordering another OBD adapter so I can check the codes again. Fwiw ..
