Hi all...

[hoochini]

Joined last night, I'm not a mechanic and I do not know much about cars but I'm learning fast... (I wish)
I'm new to MBclub and I'll keep annoying all of you by asking stupid questions on HOW TO DO THINGS... Starting now

Today I'm going to change back from K&N to standard air filters on my 500sl and maybe disconnect my battery for 1/2 hour or so to reset ESU. You see I have bought it @2 years ago and I've changed front suspension, refurbished power stearing pump, changed sparkplugs, leads, distributors, capacitors, done terra clean, changed transmission oil and filer, upgraded air filters to K&N, fixed air con, diff, new AMG wheels, new tires and repainted few panels and now it is time to look into fuel system which I think has a gremlin - sometimes when I try to "give it some beans" it seems to have a problem getting into revs, it sounds as the fuel pump straggles with fuel delivery. Don't get me wrong when I drive, it goes pretty well but from time to time when I want to get started from the stand still with a bit of umph it staggers. Is it possible that it does not get enough fuel or maybe too much of it...? Or maybe it's the air flow... ?
Any suggestions?

Hard to say. - I assume it's not the ESP kicking-in and pulling power from the car? That tends to be what happens to me when I plant my right foot too hard (although I'm learning not to do that).

How old is the fuel pump?

It may be as old as the car... 25 years old

I don't think they're that expensive (although who knows with MB), so it might be worth a try.

Hopefully one of the gurus will chip-in some sage advice.
