380SE idles Ruff
 

I have an 1984 380SE, W126. It sat for two years. I have changed the plugs, wire set, coil, rotor, distributor cap, fuel pump and filters and drained all the gas from the tank and replaced the ignition control module. The car started but when it warms up it run very ruff, almost like it was going to die. Anybody have any ideas as what I should try next?
Thanks for any help.

Does it have a low idle? If so the idle control/valve may need replacing or cleaning....
