2002 ML320 First Start Problems

When I try starting the vehicle, first start of the day it rough. It turns over but you need to gun the gas pedal to get it running, if not it stops. After about 3 minutes I can easy off the gas petal then it's ok to run. For some reasons its only the first start, once it's been running is ok. I've already replaced the fuel filter and mass air flow sensor. Any suggestions?

This is an indication that the fuel filter is partially clogged and or the fuel pump is weak.

Might have some carbon buildup in the system. Id run a fuel system cleaner through the system and see if that will help.I only mention that because you said it runs better after It warms up.

I have given it two treatments of fuel cleaner but the vehicle does have over a 180,000 miles, I'll try more treatments.
Thank you...
