Check the fuel pump relay as well -- if it's getting hot to the
touch, replace it. If bad, you should also check the current draw on
the fuel pumps, as a bad pump will eat relays from overheating.

Well the car has been sitting, but not for years or anthing. When
it gets to acting up, while cranking it to try and start it, I can
hear what sounds like the throttle air plate in the FD vibrating
every now and then/ Now what is this EHA, not sure about that one.

It is a matter on focusing on the things that change from when an
engine is cold to when it is warm. For that reason I would
discount ignition and valves.
Fuel pressure and air supply are the two main things that change,
however the main fuel pressure does not change but the chamber
pressure does.
Pinch your idle air hoses when engine is warm to see response.
Perhaps even dirty injectors.

On this new 300E i just picked up, workign out the little bugs.
It starts up and runs great when cold. AFter it starts warming
up the idle starts to get a little rough, and finally gets to
where it will sometimes die. Afterwards it can be hard to start,
or start up somewhat easier. Sometimes it will sit there and
idle and try to die, then recover and run for a little while
longer etc. Just as quick things I swapped out the coil and the
ignition module, didnt make a difference. So, seems like its
something in the fuel injection. I also noticed that it seems to
have that smell like the cat is getting too hot. I noticed this
once before in the 380SE that I dropped the 5.0 euro in. Its cat
would glow red hot I think because it was not getting enough
fuel, running too lean because the tank screen or filter was
plugged up IIRC. Wonder if this one is running too lean when it
warms up? Doesnt seem to smoke but does have a funny smell like
its either running too rich or too lean. Anybody got any ideas?
