[DML] Re: Idle adjustment screw?

Since you still have the tamper-proof plug you should not be very far
off on the mixture adjustment. You either have dirty fuel injectors or
misfiring spark plugs. You should see a nice pattern from the
injectors, not a stream or a dribble. If you don't know how old the
wires are replace them, the cap and rotor. A new set of plugs would
also be good. If it is still very rich on start-up the cold start
system may not be working correctly. Make sure that there is nothing
plugged into the Hot Start Plug by the fuse block. Make sure that the
air filter is not dirty and the air sensor plate does not rub on the
sides of the venturi.
