The warm idle speed for my 1989 300TE drops from 700 rpm
to like 550rom when I shift from Park to drive gear.
Have changed the old injectors, new bosch copper plugs, also
cleaned out the idle stabilizer valve and replaced the two loose rubber
hoses that go to the valve.
The car does not die but shakes at such low idle speed.
What could be the possibilities and what should be checked?

Thanks for your help.
