Customer Question
All kinds of problems...

All kinds of problems. I have a 2002 c32 amg and at WOT I get multiple cylinder misfires and code that read p2050-001 p2050-032 p2052-001 p2052-032 p2052-064 and so on

Mechanic's Assistant: Have you seen the misfire code before? Has the car been stalling?

No, not really. But I do remember a while back it was running very badly upon startup and almost stalling but then the problem went away and never came back. when I drive the car up to half throttle no problems, very good idle and strong acceleration. But at wide open throttle I get several cylinders shutting down randomly.

Mechanic's Assistant: Are you fixing your C32 AMG yourself? What have you tried so far?

Yes

The cylinder misfires are totally random. I have replaced some coils, checked spark plug wires and plugs, still happening. It seems like when the outside temperature is hotter the problem comes sooner but when ambient temp is cooler it is a little better.

Does this sound like fuel delivery, possible fuel starvation? fuel pump, fuel filter??

Hi, my name is***** you are only getting misfire codes at WOT I would check the fuel pressure and replace the fuel filter. A weak fuel pump or restricted filter can cause the problem. It's also possible that the catalytic converter is restricted. A restricted converter can also cause misfires at WOT. I'd also replace the spark plugs with the OEM plug if you have not already done so.

Let me know if you have any questions.

Customer reply replied 8 months ago
this would mean both catalytic converters, as the misfires are from two different banks of cylinders?
Customer reply replied 8 months ago
If that is the problem. I will chk fuel pressure, what is the working fuel pressure of that vehiv
cle?
Mercedes Mechanic: Marty, Mercedes Technician replied 8 months ago

Possibly but a little unlikely on the converters. Fuel pressure should be 60 psi.
