My '97 yoter w/ 263k was missing under heavy throttle up until about 5k miles ago when I put new plugs (dual electrode, as these motors are supposedly only supposed to have dual) in it. The miss has been completely gone until today, it started missing at full throttle again.
These motors are bad for eating plugs about every 25-30k, and I was certain it fixed the prob when I changed them 5k ago, so I'm curious as to why it misses now exactly as it did before the plugs fixed it.
Anyone have reccomendations before I pull plugs? Not to well off in gas engines. Thanks y'all
