The m103 engine needs spark plugs every year or 16,000 miles
Cap and rotor every 2 years/ 32k
Wires every 4-5 years/ 50k
Only use genuine MB parts or Bosch.
If it's been a while since your last tune up, I would do that first.

How often would you say for injectors? My 190E's motor probably has about 130K on it now. I've got some rough idle issues. Still trying to sort out.
I was putting some spreadsheets together on replacement parts.
