my e55 feels slow 7.5 0-60 no faster what the heck?
Ok guys got my e55 finaly too bad it was shipped so i never test drove the thing, maybe I got a lemon big time.
first: is it normal for e55 to cut out at 4000 rpm when sitting still?
second: the car feels honestly no faster than 7.5 0-60 like its missing 100hp
what the heck? I got no check engine light and no codes stored. What can it be?
When I floor it tranny is really lazy to shift and when it shifts there is no surge in power I think car is as fast as my gf's e320.

Sounds like you have some issues bro. Mine hauls a$$ when I step on it, not to rub it in your face. Never cuts out at idle. Also, with the torque these beasts have, it shouldn;t feel slugish. Take it to an indy shop or the dealer. That's your best bet. Then take it from there. Contact the place you bought it from. Do you still have a warranty with them? 30-60 day? If so, make them fix it, or DEMAND your money back via lemon law and find a better AMG (http://boston.craigslist.org/bmw/cto/1063103439.html) there are many to choose from, if you look...

Bummer man. sight unseen is a bad idea!
So I assume you were holding the brake and trying to burn out when it cut out?
It could be a cople of things.
1. MAF MAS mass air sensor.
2. Crankshaft position sensor.
3. Catalytic converters could be going.
4.... Something really sinister like an ignition or fuel management issue.
Drive it slow, take it to a mechanic.
There is nothing we can diagnose for you. I could literally be 20 things causing that problem. Don't beat up on your tranny. Have the fluid changed and the pan gasket and filter immedeatly.
Buyer beware 10-12k AMGs are usually auction cars that "run" and "look good"
but have passed from dealer to auction house to dealer to auction to another dealer and have low miles because they haven't been driven in quite a while.
Low milleage is not always a great selling point, mine had 90k when i bought it and its gone 30k without anything other than scheduled maintenance. I never ever buy from dealers.

also check that the switch next to the transmission gear lever is set to S not W. W is winter mode and the transmission starts out in 2nd gear.
If you're still having issues, see an mb workshop.

Lemon law only apply to new car owner. If you bought it "As is" than you're on your own. It's up to the owner to get the car inspected before you buy it. Your car might come with a 30days warranty but it always come with a deductable unless it from a new car dealership. I hope you didn't buy it from a private owner than all deal are off.
It's pretty fast right out of the box. Good Luck with the car.

i took it to a dealership today, they could not find any problem.
Suggested MAF, fuel filter.
I replaced MAF today , dealer was nice enough to let me try the part, if it dont work return it.
Well I can say that MAF helped and it shifts a little better and seems like it has a little more power, I switched old one back in place just to make sure and yep old one is worse.
I timed 0-60 with gtech today at 7.3sec 0-60 still pretty damn slow Dont know if I should try the fuel filter or not. Car spins wheels a little at first,after that sort of lack of power from 2000rpm untill 4000rpms it kicks in again..
Frustrating

Sorry to hear of your problem. What year is your E55?
Try this just for fun, disconnect your battery (under the rear seat) and let the car sit over night. Re-connect the battery and see if you notice any difference. That should reset the car to factory settings. I had a similar problem and replaced the MAF without much change until I disconnected the battery and then it ran like it should....good luck!
Here's my post on a the same type of issue.

O MY GOSHHHHHHHHHHHHHHHHHHHHHH
I disconnected the battery for half an hour and than I had to go to the store so I connected it back up.
O MY GOSHHHHHH the car feels like its a freaking jet,,,,, I was burning tires going 30mph.
so was the car in some kind of limp mode or what? cause it feels like i got an extra 150hp I kid you not
i tried doing 0-60 with gtech but kept burning rubber and spinning finally i was able to take off good but it was up a slight hill and with traction on, got 5.3sec it think Im easily in the 5s to high 4s right now....
Im so glad I bought an e55
i was debating between an m5 an m3 but now that I drove this car I would not want anything else........ its awesome!!!!
had my first kill tonight check the kill section... https://mbworld.org/forums/kill-stor...8-sti-wrx.html

Have your shop actually go through your ECU (with the Star Diagnostic tool) and totally reset all your adaptation values and the ECU will relearn everything and that alone should help out alot (this is much more than just the pedal ECU reset trick, this literally resets the ECU to basically brand new stock settings).

Mercedes ECUs have a really high adaption range and over time if you drive it like a grandma it will adapt as such and in order to really unlock all its performance & power again you have to do a reset from time to time. pedal ECU trick will do some of it, but in order to fully reset transmission and other components the star diagnostic tool is the only way.

That was nice of the dealer to let you try a new MAF. It seems they are a common problem. Before buying mine, I test drove one that just felt "sluggish" like you described. I suspect that was the problem on that car, as well. For the record, you might have luck cleaning your MAF with alcohol, rather than just replacing (particularly if it's not throwing a CEL), but I'm guessing you've already bought the new one by now.

I suspect that the way air box just sits on top of the MAF housing could be the problem. Maybe dirt or air keep on leaking into the system that way and ruin the MAF sensor , I might have to come up with a way to fix it ...

Maybe there is carbon build up. When I test drove my Clk55 last yr with 36k miles from a private seller I was like

UPDATE: after driving for a few weeks I noticed that when gas pedal is floored it takes a car a second or so to shift down where before it was instantaneous. Also I thought that car got a little bit slower but was thinking "maybe i just got use to the power"
well today took it out for a few runs with Gtech and sure enough down on power by about 80 crank hp or more 0-60 was 6 sec and 1/4 was 14.5 at a slow 97mph trap.
So I did the old trick, disconnected the battery for 2 minutes and reconnected. Went for a ride
Power is back, 0-60 best of 4.9 and 1/4mi at 13.5 and 105mph trap.
I should note that under normal everyday driving power loss is hardly noticeable, car still has torque down low but when pushed hard first sign is that there is a lag in transmission shifting.
I obviously have some sorda of a problem, either another bad MAF sensor or maybe 02 sensors?
ANyone have ideas on what this could be?
I think there is a lot of unsuspecting e55 owners who have this issue and not realize it.
I forgot to mention but I'm aware of the adaptive mode and thought that could be the culprit so have done reset for the transmission and it might of changed things a little as far as shifting but for certain would not take away 70-80 crank hp which I was missing prior to battery disconnect, trap times verify this as well that power was down.
And MAF is brand new 3 weeks old

cut-n-paste from another post..
1- If what you are referring to as delay, is actually expecting the car to downshift ( Passing cars ) faster , you might want to reprogram the Transmission, as it is adaptive and probably running on what people refer to as " Granny Mode ! Turn ignition on ( dont start the car ) , floor the gas pedal and hold it for 5 seconds, turn ignition off, then release your foot of the pedal five seconds later/ wait two minutes, then the drive the car hard for couple of miles with heavy downshifting via pedal, tranny will reset.
2- Best throttle response : Sprint Booster AMG version ( best $260 spent on the car.
