SOURCE: My 1995 S500 Mercedes Benz is idling very rough.

before you spend any more money on your vehicle run a cylinder compression test. I know it seems unlikley with less than 100,000 miles but 119 engines do like to burn valves. the LH fuel injection system was only used from 93-95. LH is a germen abreviation for hot wire mass airflow. The later systems use a hot film. Your vehicle has electronic fuel injection so why did you have the fuel injecters pressure cleaned. unless you have the cis system which means your car is not a 95. Motor mounts are also a very common failure on that vehicle. In any event rule out the worst case and perform a compression test because it really sucks to spend alot on an engine and find out it needs a valve job. I'm assuming that the check engine light is not on. although wireharness issues are another common issue. these early C.A.N. cars are very difficult to troubleshoot electronically and the information provided by the factory is difficult to follow.

It really could be any number of things. Generally I rule out ignition first because it is the easiest system to check. This vehicle has a continuous injection system that is complicated if you do not know what you are doing. In my opinion from the info, stated it sounds like you have a combination of problems. 1 most likely an airslide(idle valve) issue-possibly a major vacuum leak. 2 idle speed control issue. There is an over voltage relay located behind the battery(it is red and has a 10 amp fuse on top of it-it controls your idle speed computer and your abs computer. also if you have a high idle there are 2 micro switches located on your throttle linkage that show continuity one way and no continuity the other way. I would test those with an ohm meter to make sure they work properly. if all checks out scope test car and perform vac. smoke test to check for leaks-this will have to be done at a repair shop by a professional.

Sounds like your Idle Air Control Valve is starting to go bad. Normally I just tell people to replace it because it's a cheap easy fix, but with your particular vehicle it costs over $400. With that in mind, I would recommend either replacing it or trying to clean it with some throttle body cleaner. It is located on the throttle body and here is a link to AutoZone to give you an idea of what you are looking for:http://www.autozone.com/autozone/catalog/parts/partsShelf.jsp?categoryDisplayName=Engine+Management&fromType=parts&fromString=search&parentId=cat30067&currentPage=1&filterByKeyWord=iac&isSearchByPartNumber=false&navValue=15900207&categoryNValue=15999999&fromWhere=&itemId=prod61721&displayName=Idle+Air+Control+Valve&searchText=iac Good luck and thanks for using FixYa!

This is an interesting part, and I spent quite some time to fix the problem. I list it here those steps in the order could fix the problem ranging from least expensive to most expensive steps. It just happened to me the last one really eliminated the problem. 1- Make sure it gets turned up first. 2- Adjust cables to increase idle. There are two cables. You remove the air filter to see them clearly. a- one for the gas, the other for transmission. b- clean the area well so you can see a micro switch. This switch called cut off switch. c- whatever adjustment you make, the level of the switch has to press on the switch to maintain the idle. If you see it off, you can bend the metal part to keep it in place 3- Take off the Fuel distributor to clean the throttle below it. 4- Replace all the injectors. These are not Electronic Fuel Injectors so you don't have to deal with Injector module. 5- Replace the fuel distributors. Good luck.

2007 chrysler town & country has a rough idle but drives smooth what could it be


If it idles rough it runs rough,you just don't
notice it

You can start anywhere you want

If you haven't changed spark plugs in 3 years do that

Replace any front or upstream O2 Sensors over 100,000 miles

Check fuel pressure,tps sensor voltages,check for loose air
filter cover,vacuum leaks,loose O2 sensor,just go thru the
entire engine,it obviously needs work & I will bet it hasn't seen
much & you don't know what is done when you ask & pay
for work.
May sound harsh but many shops aren't there to resolve problems,
they throw on as many parts as the people on this site do at home,
from the questions is see here,dealers guess as well and don't road
test,kind of sad really

5.3 liter Chevy engine #1 Cylinder not firing at idle


My opinion...

Year? Miles?

There's no way I'd dive into a "HEAD GASKET"
diagnosis without pressure testing the cooling
system and (wet/dry) COMPRESSION testing
the whole engine...

Even if it is a "HEAD GASKET"... the entire engine
might be ready for a REFRESH... and tossing a new
Head gasket into a TIRED ENGINE not insubstantial
(a lot of wasted time & money)...

Come back with some compression numbers...

but don't bother with any of this if your engine oil has water in it.

Rough engine idle


you don`t say if you have checked anything so start with the plugs for condition and age as well as plug gap.then the ignition wires they may need changing.the engine compression can affect idle and give the impression its alright at higher speeds.fuel injectors if they are dirty can cause rough idle and run okay at higher speeds.just somethings to check

I just had the alternator replaced on my 240. The idle was rough before, it sometimes seemed like it wanted to stall, mostly when it was cold. When I got my car back from the shop, the idle seemed to be...


A bad altinator will not make you car run rough, This only duty is to charge your battery while running.
I can't say for sure because i don't know if you have a cerorator of throttle body or injectors. This is a fuel problem And maybe just a vacume leak. Sorry can't tell more wish you luck on it.

Idles rough but not all the time and throws up a p0440 code I trew up a cam sensor code once. I have a list of the freeze frame code problems. Fuel system 1 -- cl Fuel system 2 -- n/a Calc Load --- 8.2 ECT...


the code means something wrong with the EVAP system your cars fuel canister lines my be leaking or its as simple as forgetting to tight up your gas cap. as far as running rough.. this is kind of vague but anytime my car runs rough i change out air cleaner and plugs, usually 90% of the time this fixes the rough idle ,but for example today in fact i had a rough idle and the car has 297000miles on it and i"ve never ever serviced or thought to clean my idle control assembly before...so before i even started to take it off i found the screws were both loose...so i took it out and was so embarrassed that it was 297000 miles worth of grime on it, so i just sprayed it cleaned it with Gummout Carb clearner and made it look almost new. I just got through doing this...so i started it and it took awhile for it to reposition, because i pushed the spring in.. but now it seems to be idling a lot better. if your car still runs rough check the condition of your plug wires also.

Car idles rough in park also runs rough in overdrive


Sometimes a rough idle like that is a fuel filter. As you've already done the plugs and wires the fuel filter would be my next bet.
