What’s up gang?
The last couple of weeks my car has been running pretty rough.
I’ve replaced a bunch of stuff & still it idles a little low. Any ideas?
I have replaced:
-Fuel filter
-spark plugs
-dist. Cap & rotor
Ovp is fine, but I’m not sure about my Idle Control Valve?
I definitely think it’s related to a fuel problem?

p.s. trying to get my car ready for the 190E meet Toronto.

Rubber hoses (idle circuit, including the big rubber glove under the throttle venturi that's prone to develop hairline cracks up to no start mofos)... they fucked me up for so long... (my 2 cents... canadian, of course... :))

Hi Spiros,

IMHO, Stefan is on the right track about your problem


First thing, is a little vacuum hose from the fuel accumulator to the breather tube connected? (It is located under the front area of the air box bowl...it is a very small hose but makes a great diff in idiling!!

Then,

Last fall I had the similar issues with idling,, I tore the old hoses that go from air box to the breather in valve cover and then to the Idle Cntrl Valve.

I tried taping them etc.., but nothing worked until I got oe replacements.
This made it much much better but still not perfect..


I wouldnt even bother with dealer, I got my hoses for fraction of the price from
http://www.bestpricecarparts.com/

Good luck
Hopefully I will see you at the benz meet on sunday. I will be in a white 92 190E

clean the whole air injection system. check all hoses for cracks, clean the throttle vac lines on it can get clogged. intake gasket mite need replacement. when was the last tune up on your car? filters etc. i replaced or fixed most of those and got it running better but not perfect yet. i gotta mess with the air system more and do my plugs. money is tight, no time, gonna do what i can with what i got.

Ok, check it out?
Today I replaced the "fuel filter", cleaned the "Idle Control Valve",
cleaned all the "linkages & Throttle Body"with carb cleaner.
My dist. cap & rotor are brand new. I might need new plugs, but I did
replace them last year. Basically, doing all this stuff resulted in better
idling, but not perfect.
I noticed that if the car is cold, when I start it up, it sounds like it's
running on 2 cylinders and in a couple of seconds it clears up.
It feels like it's missing or something. Maybe, plugs, wires, I DONT KNOW, but
it's so frustrating doing this trial & error routine. Why can't my Benz
just run as perfect as my 2006 Honda Cr-V?????lol.lol.??????

Thats kind of like my car....it will run somewhat rought during the 1st few seconds then it clears up..
It is worst in the winter time!


And yes, sometimes things like that make you wonder why a benz doesn't want to run so nice when a honda can do it!

PS. Have you seen the darn gas prices lately? !!!!

old benz new honda, wait until that honda turns 15. i have pretty much the same problem with my 2.3. i have a feeling it has something to do with the cold start system, which consist mainly of the csv and the ovp. havent had time to look into it. when ever i have time its at the wrong place and i cant do it.

Thanks guys!
You know, I’ve practically have owned approx. 5-190’s, a 300CE, a 260E &
at this point I have in possession 2- 190’s. One here (1992 2.3L) & one in
Crete Greece (1993 2.3L 85,000km). I’m not bragging, I’m just starting to
think this idle problem is normal with older Mercedes? Everyone of my Benz
had this Fu^#*~ problem. Especially the 260E!
I’m saving my money & in the summer I’m going to replace everything I think
needs replacing!
-ICV, CSV, fuel pump, Vacuum Modulator, flex discs etc…………….

Sorry bro, I feel for you but I am paying $1.26 this morning, and it has been over $1.10 here for months. This is insane as the oil companies are making billions because of this highway robbery.

cheers

Ha, don't complain, man, here today the regular 98 octane unleaded litre was 1,54 cad (3,39 lei/litre for 2,20 lei/1 cad), and we don't have your paychecks here (the medium salary here is like 660 cad, not many have that luck - many only get the minimum wage of 180 cad/month - , that's why the most of the cars are on NLG)
