What do you want to say?

My next step is to put a valve before injectors, to dont back my fuell down at tank.
Although the filter should have this.

And if this dont work i try other idea.To check carefully fuell pomp and put a supplement at fuell and test my ecu at service.

The fuel valve wont make any difference as the rpm are low and not on cold start high idle, the problem lies elsewhere, as I already said I would look at the ECU flow meter.

I would also check the timing.

If it has fuel and spark it will run. If it's at the incorrect time it won't.

Olly Jonson CM30 pumps in stock for 55k engines.

Same problem on startup idle low then continue good. W168 has plugs so sensitive that like to misscontant. Pull out maf both plugs, actuator plug, spartplugs plg and another plug under tha maf...so all plugs follow tha maf plugs main cable. Spray wd40 in all both ends and re plug everything. Spray caburator cleaner in the maf sensor and in you can follow youtube and clean actuator. As i said w168 plugs love loose contact. Startup and go.
