Sorting out E320 stalling problem

Help, Low-RPM hesitation and stalling @ idle???
For about a week now my cars been acting up, mostly when the engine is hot (operating temperature), there is what FEELS like a misfire or fuel cutting off, only from 1k to 2k RPM, like the engine is shutting off, but if you hit the accelerator it seems to catch and run fine once the revs go past 1500 or 2k. Also when at a stop or sitting at a light idling the engine tends to turn off after a few seconds. Also sometimes at freeway speed, with partial throttle the engine bucks, again, like a fuel or spark cut off, but just for a split second.
does this sound like a CKP issue? the engine never fully failed to start, only hesitate and cut out at low RPM.
Also, my cat is dead, it used to rattle, but now it stopped rattling, could it be clogged?
Could the fuel filter be clogged?
Plugs? Wires?
I do have the CEL on but its pretty intermitted, it seems to turn off every few starts, even immediately after a stall out. I lest out my OBD scanner and I still havent gotten it back, but should pull the codes later on tonight.

maf
Mass air flow sensor could be dirty. Member gregs210 did a great DIY pictorial on cleaning the MAF sensor with CRC MAF cleaner, which is available at your local auto store. Do a search on his posts and it will probably get you to the DIY.
Since you mentioned that you're going to try and pull codes, they will most likely be stored even if the CEL light is not on.
Hopefully the MAF cleaning will fix your issue - it did on mine, but then again if you've had previous trouble with your cats, it could be past the MAF and you may have a plugged cat.
Not an uncommon issue with our cars, so if you have time do a search around the forum - lots of good info to be had. Best of luck.

May also be Crank Positioning Sensor. These do go bad. Location is at top rear of motor. Attached by one bolt with no adjustment. Just unbolt pull and replace. Order from Autohaus for $40 or from dealer for $150. Did mine last year at 70K miles. Its a 10 minute DIY job and very easy.

X2, try replacing the CPS first. Cleaning the MAF is another good idea. Then I'd investigate the cat that used to rattle and now does not. I had a plugged one on another car and the symptoms were somewhat similar to yours.

Come on the obvious
folks. The op states he has a bad cat it was rattling. And stopped.
They don't mend themselves and symptoms indicated exactly what a failing cat does.Start with the simple stuff.
it's not the maf,it's not the cps,it's not air,it's not fuel............................

its most likely ur cat bro. my friend had the same problem and it got worse with time. when i dropped the exhaust from cat back(both cats) the misfire was gone. as OhLord said... a rattling cat is obvious. it will get worse with time and most likely affect ur O2 sensors if not taken care of soon. good luck.

I replaced the original MAF about 12k miles ago, because it gave the p0170 p0173 codes, even tho the car ran completely fine, but I needed to pass smog. I picked one up from ebay, I was told it was the bosch one, but it was just a "bosch type" when it showed up.
I ran the scanner a few days ago and p0100 and p0161 came up. I cleared it, but p0100 came back almost immediately. The p0161 has not reappeared yet. Just to rule it out, I'm going to go to NAPA and pick up a REAL bosch MAF, and see how that goes, if the codes reappear, I'll return it.
Heres a few things that happened before this issue started. When I was getting gas on a near dry tank, I was only able to put 16 gallons in before the filler nossle clicked, I forced another additional 1.5 gallon in there. Could that maybe clogged some evap or vacuum line up thats keeping the fuelpump from providing enough fuel pressure?
I'm leaning towards the cheap MAF, because when I unplug and replug it it seems to make the car run better for a short while, 100 miles maybe before it starts turn off on me again at every stop.
EDIT: I just checked the scanner again and it pulled up p0100, p0161 and p0156. Could the MAF be causeing the bank 2 heater and sensor malfunction codes? or could everyhting be related to the 02 sensor and not the MAF? could the 02 sensor trigger the p0100 code?

It was the MAF, fixed the stalling and hesitation problems, but the CEL is still on with the P0156 and P0161, so I'm guessing that my left rear o2 sensor is gone, along with my cat.
cur runs fine now tho.
LESSON! dont buy parts off ebay!

Glad you got it sorted out. FYI - Most auto parts sellers won't take a return on electrical components.
However if your cat was rattling then chances are very good that the substrate holding the catalyst has overheated and disintegrated. Usually this leads to a plugged cat and engine power issues.

mercedes 2000 e320
e 320 shut off engine
I have a Mercedes 2000 E-320 with about 165K miles without any problems (until now!). It happened two weeks ago. I was picking up my son from swimming lessons and on the parking lot my car wouldn't start. I turned the key to start my car and it wouldn't start. I tried it again three times and it still wouldn't start.The starter works how it's supposed to work. On the 4th time, it started without any problems. Yesterday I was going to the Lowe's parking lot to see a guy. I talked with him for 5 minutes, and after that it would not start, AGAIN!!! After 3-4 times trying to start it, it started but, when I drove about 200 feet to the stoplight, it shot off. It started on the first time I tried to start it. After driving about 1 hour to go to a different stoplight, it shut off again, and started from the first try. The yellow engine light on the cluster panel is not on. Do you guys have any idea whats wrong?

Change your
cps crankshaft position sensor.
Has nothing to do with your tune up or plugs.
diy on www.benzworld.org w210 section.
cps about 60 bucks and a half hour of your time to r/r

The wife's 1999 E430 sport is experiencing some wierd problem and I have been unable to solve. This morning I took her car to work and was driving through traffic about 30-40 mph, when an ESP light came on immediately following the BAS light came on, then the engine shut-off while in drive in the middle of traffic. Turned the key off and tried to start on 7-8 different times but unable to fire up. After about 10 frustrating times the car finally starts and I make it to work with no more dash error messages. This also is what happened to her yesterday while driving.
5 weeks back the brake light switch due to ESP/BAS malfunction was replaced and along with MAF when engine light came on was also replaced in the same week. This seemed to work and no lights until this week.
Other than those two (2) issues the only things that have been done is oil & filter change, transmission filter and oil change, rear end oil changed, fuel filter replaced, air filter replaced, new spark plugs and radiator flushed w/new antifreeze.
Anyone experience this before where your engine dies while in drive then starts minutes later?? Any idea what this problem could be? Any fuse related issue that I need to be concerned with?? Took it to local repair mechanic to obtain information off his OBI II scanner and read nothing.
Really puzzled and was hoping to avoid trip to the dealer as our local MB dealer takes real good pride ($$$) in their service work. Any help is appreciated.

my '02 has a 40 amp fuse ( a big orange one) that was blown and I got those same errors...replaced and no problems since. loog at the list on the fuse cover sheet (under the hood) and look for BAS and ESP.

MAF CPS Preventive Maintenance?
Hello All, and thank you for building and maintaining this insightful resource of knowledge and experience around the MB product lineup.
As the new (2me, 7 week) owner of a 1999 E320 I'd like to ask if it makes sense to replace the MAF and CPS sensors as a measure of preventive maintenance. I have not experienced any hard starting or stalling issues, however if it makes sense, I don't mind replacing these components in advance. BTW, I purchased the car with 193K + Miles and have since replaced the timing case expansion cover and gasket, and changed all (sans PS) fluids. The work so far was done by a local indie shop that has enjoyed great reviews. The car runs great with the exception of a very mild rough idle while at stand still in drive (stop light). The local indie guy's told me that engine mounts are slightly worn, although not in need of immediate replacement. They also recommend that I run a bit of Techron through the system before shelling out $1200 for a major tuneup.
Any insight is most appreciated!
Thanks again!

I would not replace the MAF or CPS sensors until they go out...you might buy a CPS sensor and keep it handy but you never know if you will need those parts...and you could sell the car or it could get totaled tomorrow, etc. I would not throw money at something until it needs repair.
You rough idle could also be fuel injectors...that was a classic symptom with the older models...rough idle at traffic lights....a set of new fuel injectors and they run like new again.

Sir Mike,
Thanks so much for your shared insight. Your suggestions are well received and make a ton of sense. I'll go ahead and grab a CPS and keep it handy. Also will search "fuel injectors" to learn more about this characteristic symptom.
Much appreciated!
Thanks again,
Tory
