I m sure many of you have experienced a similar starting issue.

I plan on replacing the following -

Distributor cap
Spark Plugs
Ignition coil (this car only has one)
Front Crank position sensor (are these known for going bad)?

Considering the Rear CPS too but not sure how much more difficult that will be to access. Is it better to replace these in pairs?

Any suggestions or advice from the more experienced folks with this engine would be greatly appreciated.

The car is a 1992 300CE with M104.980 engine. Other than this starting issue and the occasional lumpy idle when the engine is cold(sat overnight or days), it runs great. This starting issue is sometimes random, sometimes the revs will drop like in the video but the car wont stall, it will figure things out and idle normally.

Thank you in advance for your advice and suggestions
