Check engine light

[Gregory OConnor]

Reduced speed limit implies a low fluid level reading and not a
damage report. Is the puke sight glass clean???? put a wrench on it
and take it out to see if it is truly full or just add 1/2 gallon to
it. Tach may be a completly seperate issue. dont rule out that
possibility. Dan gave good advice on cleaning things and looking for
worn insulation or carbon marks on wires
Seedsman? are you an Agronomist?
