2000 Mercedes E320 fuel pump maybe?
My lady ran out e320 out of gas! She put gas back in it
and drove and it started running rough, losing power, and
stalling. I got it home and changed the fuel filter, filled it
with premium and gum out injector cleaner. I’ve driven it
about 40 miles and It runs much better but still isn’t right.
As long as your light footed it will slowly accelerate but if
you try to give it more gas it loses power. I believe it’s not
getting enough fuel. Called oreillys and they said $230 for
a pump. I see them online much less but want to buy a
quality one.
