[DML] Re: Missing idle mixture screw?

["Bernie" <bmanderville@xxxxxxxxxxx>]

Is the missing screw in the intake manifold or on the fuel 
distributor?  That would help all of us to help you.  If it's 
missing from the intake manifold, you have a major vacum leak.  If 
your fuel distributor doesn't have some kind of plug on the 
adjustment screw hole, you have a vacum leak there.  You will need 
to plug it, a golf tee will do the job, just make sure you shorten 
it to only plug the hole.  If there is no screw way down inside the 
fuel distributor, then you have another problem, but I doubt this is 
the case.  I would think your car wouldn't even run if that screw 
was missing.

Once you replace the missing screw, you will need a tune up, as the 
fuel mixture is going to be totally off.  What do your spark plugs 
look like now?  You have replaced them, any signs of rich running 
would show up and you can fix the problem.

25 bucks for an emissions test, what a rip off, does your state 
allow waivers if you spend x amount of dollars trying to fix the 
problem?  If so you should be OK if you just show your reciepts for 
all of the parts you have replaced.
