My E-38, 2001 740IL is not runnig well. Can anyone tell me how to make something to perform a smoke test with and how to perform the test? Also I was looking for information on how to change a device that in front of the spark plugs, my #8 is showing bad (I can't remember the name of the device but it's not firing well)?

Thank you in advance for all replies.
