Just had my 6yr service done at a ETEC Auth Dealer and received my Engine History Report. Wanted to ask why the Eng Hours 376:24:17 is so different than the EMM Hours 120:39:4 The dealer says after he spoke with his ETEC- Support Tech they said it just happens sometimes, yet could not explain why. Said it could be that I leave my key in with it "ON". I do not do that and I have always owned this engine after purchasing it in 2012 and never had the EMM replaced. Not sure what is up here?
I have not seen it but have heard that excessive RFI from arcing plug wires, faulty sparkplugs or super worn ones with large electrode gaps, incorrect wire routing, etc. can affect the key on timer if you are positive that the EMM was not replaced.
