Unhappy rough idle...sometimes?

whats up guys having a problem with my 300e. I use the car as my daily driver and it runs beautifully but on the weekends i usually park it and drive one of my other cars. lately after i park the car for more than two days when i go to turn it on it cranks longer than usual before starting and when i stop at a light the car idles really low and rough even turns off some times. but if i drive the car again the next day it drive perfectly the cars due for an oil change but i doubt that's the problem

Any idea what would cause this? i'm thinking the carb is dirty

No carb on your 300E. Start with the basics....when was the last tuneup done? OVP replaced in the history of owning the car? Once both of those are 100%....90% of the time all running issues will be resolved.
