Haven’t checked the voltage to the
injectors yet; so I can do that.
Checked - No vacuum line leaks; no lines
out of place. Leak in MAP line would give a higher MAP reading and too rich a
mixture.
Checked - No air leaks – would take
a major leak downstream from the
injectors to give these symptoms.
Fuel pressure is normal.
Did you try both controllers?
Tried both controllers – same behavior.
Looked at the mixture correction table on the EM-2; things look normal. The
mixture “map” would have to be WAY off to require ‘cold start’
switch on.
The only thing I noted as abnormal was
that the EGT on rotor one was not stable; seemed to be ‘hunting’
around the values of the other two. Since the engine was running smooth
and steady, I attributed this to something related to the TC, like poor
connection, TC going bad, etc. I can find no connection between this and
a way to lean mixture w/o cold start switch on.
