Sorting out E320 stalling problem
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.
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.
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............................
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?

cur runs fine now tho.
LESSON! dont buy parts off ebay!
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.
Has nothing to do with your tune up or plugs.

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.

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!

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.
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
