How can i temporaily quient down noise on cat converter on my 2001 e 320? Is there a simple solution until i can replace

check that is not a rock or something between the cat converter and the heat shield. Other than that there is not much you can do except replace the cat because if the noise is coming from inside that means that the cat is broken and will block up the exhaust causing problems

Random multiple misfire code. Cat gets glowing red hot. Sluggish lack of power/acceleration

Combining the hot cat converter and the missfire code, I would lean toward a fuel problem. Too lean or pressure too low.
If it was an ignition problem the cat would usually not be hot.
If the exhaust was stopped up, you would not usually get the multiple missfire issue. Just lack of power.
It could be a leaking EGR or other vac problem, and a dirty fuel filter too.

What o2 sensors are needed for mercedes ml320?

There are two sensors. One is called the pre-cat sensor part# 0015406017 and the other the after-cat sensor part #0015403717.

I don't know where you live so can't tell you any specific websites. But the o2 sensors list for about $248 from the dealer. You can buy these aftermarket for about $50 for a Bosch sensor.

New cat vs a O2 Sensor

The easiest way to see if a cat is working is to measure the exhaust temp before and after the cat. If the cat is working the after temp will be less than before. We use an inferred heat gun.
Not sure what you mean by pulsating. If your truck is a V-6 you might be able to switch the bank 2 sensor with the bank 1 to help diagnose.

My car feels like it might die when Im coming to a stop (very slow, at less than 5mph) I can see the headlights dimming. My car is reading code p0420 which could be a bad cat. Would a bad cat cause my car...

No it may also have a bad or blocked cat though. It sounds like the alternator needs to be replaced or that the belt may be stretched or broken therefore not doing anything.

All your cats are ruined
All your O2 Sensors are ruined

Now you need to find out why the cat failed, in less than 15 years
BEFORE you replace them all.

What does-just did an engine mean?

For the converter to be red hot, the
timing chains are out of wack or
your putting a lot of raw fuel into them

I have a 1993 ford f150 how do I know if the cathalitic converter is bad my truck had lost power and gas don't last much as before some one toll me that may be the problem

Yes it could very well be blocked inside and a vehicle of this age i would say its highly likely ,their is only one way to find out and thats to remove the cat and fit a new one they are not that expensive anymore like years ago .or try another one from the scrapyard and if that works then knock the old one out of the silencer and use that and only fit the good cat when you take the vehicle for test as with no cat it will greatly increase power and use less fuel .

Losing power going up long hills it has to be a long one otherwise car runs fine could it be the torque converter or something else

Depending on mileage you could have a cat problem. Have the exhaust back pressure checked when the cat is fully warmed up. It may be the cat overheating on a long grade.
