W211 05 e55 amg stalls /jerks
More fun , my 05 e55 stalls and jerks when i go WOT feels like i hit a rev limiter, details..
Stock:engine,ecu,tcu
Mods:010 aux pump,muffler and resonator delete, x pipe.
Things i have changed and checked already: sparkplugs changed and checked,vacuum leaks none,no codes.
Things im checking soon:order new ignition wires,checking fuel filter,fuel pump.
What the car does: car stalls and shakes bad when i go WOT like a rev limiter at any gear from a roll or a digg any rpm etc as soon as i go straight WOT.
So if u have input as i work on this im all ears so i can get to the bottom of this case faster any welcome.
0 codes drove to vegas 3hr drive no codes car runs smooth and shifts smooth when crusing normal but as soon as u deman it to go at wot bam stall stall jerk jerk jerk if u let off the pedal and get on it again it corrects it self at times it wont do it but for most part it does.

Pull codes and check your trims
That was my best bet pumps or filter, i have no info on previous owner or its abuse or maintenance the car does feel like *** tho i mean its smooth but it does not feel like a 470hp car my s4 with 350hp feels 200 times better so im sure something is wrong with the car.
I had a similar problem when I left a jumper in place for the IC Pump during a 1/4 mile run. I had pulled the relay and put in a jumper to keep the pump running between rounds. I left the jumper in and the car went into limp mode. Removed the jumper, put the relay back in, and all has been well ever since. Still don't understand why, but that seemed to be the culprit.

Interesting something worth looking at , right now my guess is its ignition related or fuel related, worse case scenario torque converter if so i might just go aftemarket and drop the tranny but well see. Or like someone mention that star program is a good idea might get that when i get payed saw it for like 800 bucks not bad i have the vag for my 2 audis but star sounds like a handy tool worth buying.

Update
Ok so after running the car few times i notice something when the car stalls or jerks the little triangle on the dash flashes its the esp i think, however it does not always come on and when i disabled it car still seems to do it, today im getting under the hood see what i find ill update later today.

Update x2
Ok so new wires, new coils are in shakiness at idle is virtually gone now. I found a ripped on one of my tubes also the idle pulley dual one has a piece missing broke off.
Im going to run it see what it does and go from their,next is fueling then gaskets in the sc and then intake mani gaskets.

Yellow triangle indicates wheel spin. I am not sure of your description "stall or Jerk". Are you talking about the 1800 RPM supercharger engagement, it is more pronounced the more aggressive you are with acceleration. depending on conditions anywhere from 1600-2200 RPM the supercharger comes on line and causes a load (15-20 HP) then builds boost and brings horsepower up fast, 400 ftlbs of torque @ 2000 RPM is possible.
Now if you are running at 2500 rpm 5 gear on the highway and drop down to third gear and punch it and it falls on its face, that would most likely a fuel problem, the E55's fuel system has many short comings, the tank is crap, the fuel pump is not the greatest and has been known to overload the electrical plug and melt it, the filter is a whole other can of expensive worms.
you really needed to start you diagnostics with fuel system because the M113 twin plug ignition system is bullet proof and the ECU is much more accurate reporting ignition problems (codes) than fuel problems.

Good info but no seems when i go wot the car stalls bad like a if i cut the fuel suddenly sometimes i go wot and car wont go anywhere just sits there and sounds like its running rough even the exhaust note changes at wot

Still should check fuel pressure.
TPS, there is a good thread here on the topic of Throttle Position Sensor, I just cant find it right now.
You could try the ECU reset and or disconnect battery over night.

Funny thing is i been running the car since the coils and wires change and it has not done it so far, but let me ask u this when the car reaches high temperatures the sc wont work correct ? But how does it feel ? Bc coming from vegas felt like the sc clutch was engaged and disengage rapidly when i when wot so i felt the car kick over and over like when the clutch engages

SC off feels like a V6, If you have high inlet air temps the ECU pulls timing and if they get too high the SC gets shut off. You might want to check the Intercooler pump it is a known problem on these cars, 100's of posts on the topic and newer better (updated Bosch) pumps are available.
BTW no code for bad IC pump.

Funny story tho i just swap that lol its new 010 pump and it already had a 010 pump xD , so is not that i think intercooler is clogged tho the fins are all bended and dirty, at what iat does the sc cut off do u know?
its shuts off around the 170 degree mark. if the esp light is flashing when it happens there is a good chance there is a stored code in the esp module so it would be a good idea to get hooked up to a star and read all the codes.

There we go now we getting somewhere this is good ifo , well at vegas was like 108 so maybe the temperature inside the sc was greater than that, my esp light goes on when i lose traction bc one of my rear sruts is completely gone needs replacement =(.

strut or shock? im confused if you have your air strut completely gone/collapsed how are you driving wot?
Sounds just like what happened to my E55. Did the problem start after it not being driven for a while? Or after having the Batt discharged due to whatever reason? My E55 was jerking and just dying after being run for some time. Sometimes when I put my foot flat on the pedal it would start jerking too…… Crazy thing was I took it to the local Euro specialist for a Diagnostic check, all sorts of electrical codes came up. I replaced the main battery even though it was giving good enough readings and that fixed the problem flat! Some electrical gremlin manifesting its way through the battery. I’ve done over 10k in it since then with no further issues.

I just jumped ahead lol
