Make sure all Ignition coil drivers are wired to the correct cylinder.

Load test the Coil grounds, I use a Halogen sealed beam headlamp, Then check ALL ECM grounds.....Not many with a E38.

Load testing is the ONLY way to truly check a ground. If you need help on test procedures, Let me know.
CB - Whats the procedure you use for the load test?

Last night I did a compression check on all 8 cylinders just trying to eliminate any possible mechanical problems. All cylinders were 215+ psi. Friday I will do a smoke test to make sure I don't have any vacuum leaks. If that checks well, I'll start digging into the wiring....
