How to determinate which cylinder is misfiring?
I have a problem with my c36 amg -96 wich have a misfiring on idle when the engine getting hot. How do i see which one that is misfiring?

Out Of Control!!
Typically a misfire will produce a fault and therefore the CEL would light up and then by using an OBD reader you will be advised of the applicable misfire fault code---Is your CEL lite???

This is the item i use to check for faulty spark .
Ebay item in UK so you may get them in the USA also i bet they are made in China. -Ingnition Indicator Testing Tool . Just pop it on the wire to see it sparking .

My car doesnt't have an obd socket. It's the 38 pin socket and i only have access to a autocom code readers which doesn't say anything which cylinder is misfiring. Can it be something else that might causes the same symptoms as a misfire but is something else?

Since i only have access to a autocom scanner and here is the dtc i got these troublecodes
DTC Description
132 - ECU fault
156 - CAN: Signal from ETS/ABS - abnormal signal
133 - Throttle potentiometer
136 - Throttle potentiometer
196 - Unknown fault code
140 - ECU fault
158 - CAN: Brake information - Implausible
144 - ECU fault
157 - CAN: Signal from ETS/ABS - abnormal signal
133 - Throttle potentiometer
137 - ECU fault
140 - ECU fault
163 - CAN: Signal from EZS - Missing
And as you can see it's kind of hard to narrow it down and determinate the reasons for the errors.
I should tell you that i already tried with 2 different throttlebodies where i assume the throttle potentionmeter is located at and it didn't work. And 2 diffrent e-gas-module and the same.
I'm starting to running out of options.
I can't choose the model c36 in the program so u put in my VIN number and it choosed the closest which is a c280
Is there a cheap scanner i could get thats actualy narrow it down to a specific component. Because ECU error doesn't make me any wiser

ZIB Your first post was to find out whitch plug was not fireing was it not.
Now you have gone to the fuel supply. Did you check the plug leads for spark? You need to find out if it the one or the other..Or to find this fault will go on for ever.

Well if i'm listeningen to the engine one the idle it's shaking and i believe it has something to do with a misfire on one of the cylinder?
But if you check with a scanner it say something about the ecu and throttle position sensor.
That's why i'm a little confused myself. I have checked sparkplugs and they all look exactly the same so no unused gas or anything on the sparkplug. if i'm remove the any of the it's the engine starts to shake even more. So it's spark on every sparkplug.
Does anyone know what kind of problem we are looking at on the faultcodes for
CAN: Signal from EZS - Missing
CAN: Signal from ETS/ABS - abnormal signal
can this cause problem with the engine?
The ABS and the ASR light are off.
Do anyone know any cheap handhold scanner that really works with the 38 pin connector

Zib Can you get Google Search ? If so put this in the search box-
Mercedes C220 Signal from EZS missing. Lots of information on Google . The other ETS is electronic tracking system

First of all, what does c220 have to do with anything?
And if i were able to google evertyhing why do we need forums?
Can this 2 thing impair the idle on the engine?

ZIB i have looked and i can see your talking about another car and engine .I went wrong and took the car from your profile. As for spark problem i think now you have a major problem, i wish you good luck with those codes it looks bad.And i dont think anyone as the info on here to just say what it is .Take it to mercedes and get a star readout .You dont need help from me. Swaping things out and that are probably not the right parts.
