I got this info from an engineer who supposedly worked for Champion. I'm beginning to have my doubts about his qualifications based on the post you just put up. Maybe this is why he doesn't work for them any more? (if he ever really did - I got to talk to him on the phone & although he seemed mostly competent, he did strike me as a bit elusive in his response to certain questions - I don't know him personally). I did not research further to verify his information since he was supposedly well versed in this field, & DB & Ken needed answers ASAP.
I'm just happy that the miss problems that DB & Ken were having seem to be resolved, but time will tell for sure. Interestingly, the suggested solution for both scenarios turns out to be the same - change the plug wires along with a new set of plugs.
Thanks for your informative post by the way. I am always open to additional info since I am a back yard mechanic and no expert on cars. I also appreciate your gentle delivery! I'll take time to verify second hand info before I post in the future, or at least qualify it and/or add a disclaimer.
Ken & DB, I apologize for leading you down this road when I had no clear view myself. Things seem to be working out well thus far, so we are lucky there. I will double check my sources in the future.
