Re: [DML] Re: Idle adjustment screw?

[stefan diklich <stefandmc@xxxxxxxx>]

Thanks Dave!
Will adding fuel injector cleaner give me a good chance to have the injectors cleaned, after all the car only has 21,000 miles on it? I just bought a new cap, rotor and wires this week and i put new spark plugs in a few months ago. So the cap rotor and wires will be on soon. Can you give me a bit more info on the Hot Start Plug and what it looks like. I looked near the fuse box and dont know what to check. And last how do i check that the air sensor plate does not rub the sides of the venturi (dont know what the ventur is) Thanks for your help

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.
