2001 E55 Vibration/ Jerking
when I am in drive and I release the brake the car hesitates like I’m like a clutch out without the gas. When the car gets up to walking speed the jerking goes away. It feels like the car is about to stall but the Rpms don’t move. Brand new plugs.
Also need to know the part number for the o2 sensors that are after the cat.
Thanks

Plug's "should be" Bosch 7422 "Platinum" single electrode - if you're talking about RPM is "jerky" and 800-1200/1300 RPM feels like it's choking/stalling - then that can be sign of failing/out-of-spec Mass Air Flow sensor (MAF) consider replacement with genuine Bosch 0280217810 from a reputable internet seller - that MAF gets a lot of heat back their when replacing MAF get a fresh MAF gasket from the dealer since the old gasket dries out and tends to be leakey - consider fuel filter replacement genuine Bosch or Mann filter only (also takes 4 hose clamps to replace the trickster MB OE clamps) - then fuel system cleanup with 1/2 $9 bottle Stabil Marine Fuel Stabilzer (Blue bottle) - and fresh air filters (2) Mann 1040940104 or Hengst E827L only ... all and all like $140 for MAF - $7 for MAF gasket - $45 fuel filter - $5 clamps - $9 bottle Stabil - $30 for both air filters - gets you started on the right track.
If it's "vibration" when taking off - then check engine mounts - consider replacement with OE or Lemfoerder...

This could be a vacuum leak as well. It will affect top-end power, but will be most pronounced just off idle. Did it throw the check engine light? If so, any DTCs?

What are some maintence I should do? I did oil change today plugs the other day. What else should I do? Car has 173k. Trying to make it perfect before I put it away for winter.
