2007 300xs Coil Questions
I was recently talking to Wildman about some widely varying performance numbers with certain props I've been trying out. He said some of my numbers don't make sense and after some conversation he suggested maybe I have a coil problem.
I test COP coils the old way- with a timing light. It's possible I have one or more working intermittently. I'm first asking if this is even possible. Seems to me they work or they don't.
I'm looking for informed opinions and suggestions. On coil testing, or anything you might want to contribute.
Thank you in advance for the response\\\/// \\\/// \\\/// \\\/// \\\/// \\\/// \\\/// \\\/// \\\/// \\\/// \\\/// \\\/// \\\/// \\\/// \\\/// \\\/// \\\/// \\\/// \\\///

About the only advice I can offer:
1. They can definitely be intermittent, or only act up under load.
2. Have fun and good luck!

Pull them off and looks close for cracking or swelling. Buy one coil and install it. If it runs the same then move to next cylinder. In the 10 years I owned my 2007 300xs only had 2 coils fail.

If I have an intermittent coil failure would the plug likely look different?
