Sometimes Very Hard Working M103

Got W124 300E 87 120.000miles

When i replaced injectors o rings its hard to working sometimes
At the mornings or completely colds,it runs perfect at single crank.
But when the engine hot at normal operating temp.its really hard to start.
I changed thermostat and another temp sensors and nothing to change.
Any advice?
Sorry For English
Best Regards.

I had exactly the same problem.

I changed the fuel accumulator - it's back by the fuel pumps.

After changing injectors and injector o rings car now idles as smooth as silk.

Fuel pressure incorrect, coldstart valve leaking, Airflow sensorplate rest position wrong, lambda control faulty. Check residual fuel pressure. Could be the check valve at fuelpump.

Good advice there. M103 hard warm start can have multiple sources.

English may be a bit rough still, but apparently having no difficulty mastering the profanities.
