-----Answer-----
Question:
This has me confused.
The 300E 3.0 was not imported to the USA until 1986, which would make this a (nonstandard) Grey market import, and very difficult to find service data.
Chassis W124.030
Years 1986–1992
Model 300E 3.0L
Engine M103 I6
Body style sedan  

Best advice:
You have a minor starting issue, begin looking for a vacuum leak and treat the system for dirty injectors.
This needs hands on diagnosis for lowest cost repair.

I would contact (join) the Chicagoland Section Mercedes-Benz Club of America can help you, they are extremely active, offer great advice and know the best repair shops near you.
