Thank you to all of you for the info. Sorry I am so late getting back to you. I washed my 6.8 (the engine itself) the other night to get the road salt off and have now learned NOT TO DO THAT. Trying to find the bad coil and/or plug on a v10 is like playing whack-a-mole at Chucky Cheese.
Juneau76 I may take you up on that keyless system once I see what my current damages$$$ are.
