Agressive pedal is not anymore accurate.
Now anything more than a feathered pedal causes misfire.

1999 ML320, 120,000 miles. replaced plugs, fuel filter and pump at 100,000 miles..and cleaned erg tube. CPS replaced at 90,000.
cleaned air filter last night. mass air flow replaced this week.

I drive like a grandpa. last week i thought i should open her up a little...nothing happened when i pushed the pedal half way down...no rpm increase no acceleration. ..then it felt like it was hitting on about 3 cyl and the check engine light came on. I tried it 3 times, 3 times this happened. I turn the key off and it will start back up running on all 6...If I take it easy I am ok. My buddy says replace the gas filter again. I thought I would post here first. I have more updated posted down this Thread.
