C240 feels like it wants to die at stop

Hey everyone new to the forum here but long time lurker. So I have a 2003 c240 sedan and Everytime I pull up to a stop light or stop the car feels like it wants to die. The rpms dip and shake the car and it only does it in drive. Sometimes I have to put it in neutral at a stop to get it to feel normal. I'm getting really tired of replacing stuff that's not working and I've replaced a lot of things mentioned in this forum from other post and still nothing. Things I have replaced and fixed are fuel filter, purge valve, crank position sensor, spark plugs, wires, coil packs, maf sensor, air filter, oil change, cleaned ever valve, replaced all my vacuum line, replaced valve breather hoses, and still does it every single time. It has no codes other then the abs right rear sensor which is the tone ring because I replaced all the abs sensors. And once in a while my check gas cap light comes on even though I replaced the gas cap and it still does it. Any help would be appreciated I'm just really confused especially since I can't pick up no codes or anything on my reader.

Check the fuel pressure on the rail on the top of the engine. There’s a schrader valve and you can rent a gauge for free at Autozone. Do that and let us know what the reading is and we can take it from there.
