More on 'check engine' light
Thanks for your suggestions. When the problem started I suspected fuel
quality problems ... been holdin' out for lower diesel price for way
too long. Fuel drained from Racor revealed chunks of algae ... changed
both filters, put in Bio-cide, & $614 of diesel. Still get the
intermittent 'check engine' light on constantly which causes tach to be
inoperative & speed to be resticted to 37 mph. Next time I switch it on
the light will function properly & everything works normal.

When the light works correctly & I read the DDEC II codes with
the 'test engine' switch I get 16, 31, 32, 43, 44, 64, 66, 68, & 85.
You'd think it was near death ... Cranks up & comes 75 miles without
missing a stroke. Next morning all fluids are OK, cranks up & comes 100
miles to home without any problems. Switch it off & back on & 'check
engine' light stays on.

The pattern when giving problems is: Initial turning on ignition -
'stop engine' light does NOT come on momentarily but 'check engine'
light stays on constantly. Tach doesn't work & speed limited to 37 mph.

re: the question about me being an agronomist ... if I had $$$ I'd hire
someone to fix the problem instead of trying to steal ideas from
you "master mechanics". naaaaa ... I'm in the seed cleaning &
distribution business. A "tinkerer" also ...
