Default HELP My car has a mind of its own!

Hi again, once again i,m looking for some experienced help with my 1990 190E 2.6 auto. Here's the story, If my car is used every day i have no problem, but when it is not run for a short time, now getting down to about 1 day, it is a nightmare. Starting cold it starts perfect and runs perfect, but when it gets to full temp it runs lumpysometimes stops and will not start at all, not even an ignition fire untill it is left to fully cold again. It it does start, it will not pull away, on acceleration it just sits there bubbling and goes nowhere. I am thinking whether i have a fuelling problem, something sticking or jamming, or i have a relay sticking. Anyone with some information or experience with a similar problem, any help will be much appreciated.
Thanks, Mawbs.

When it won't start do you have a spark?

CPS Crank Position Sensor (on bell housing) is a probable cause.

There must be something clogging in your fuel system. Might be the fuel injector. Go have it checked asap
