reving engine on 1999 S500
it looked in decent shape, but i wasn't able to drive it.
however, i did rev the engine a bit - both in P and also in Neutral.
the sound was fine up to 4k rpm, but the engine was rough/hiccuping at 4k+.
is that normal while the car is in Park or Neutral?
it didn't seem right, though I usually don't rev engine at P or N.
just curious what you guys owners have experienced.
p.s. anything else that I should check out?
only thing i noticed was auto door lock and rear headrest buttons on dash not working.
thx.
Patrick
