Tractor hasnt to missed a beat in 4500 hours. Stared it Saturday sputtered missed blew smoke ect. If it idled at all started doing that. Under load seemed fine. Ecu44 came up erratic enugine speed input.
Dealer came grabbed it and thought 3 and 5 were missing so changed injectors. Now it idles fine but crap under Load. They already checked crank and cam sensors. Now going after toning wheel on crank. Thoughts? I am certain now it didn't need injectors but I guess you learn. Anyone ever have similar problem?
