Are there any issues with my 1995 C220?
Been having ongoing issues with my 1995 C220 with 150k miles. 1) Very rough idle and sometimes stalling when putting into Drive or coming to a complete stop while in gear. 2) Very rough acceleration when applying more than 50% throttle from a standstill. If accelerating with very gradual throttle application (10-20%) then smooth as silk.
How to troubleshoot your Mercedes Benz air conditioner?
Identify the location of your compressor. Look at the pullyer and you should be able to see if it spining or not.

The C220 is fitted with a 148-hp 4-cylinder engine, and the C280 has a 194-hp 6-cylinder engine. Customers seem to believe the added power, torque (199 lb.-ft. at 3750 rpm) and smoothness of the 6-cylinder engine are worth the premium, as the C280 outsells the C220 about two to one.
What was the price of a Mercedes in 1995?

What kind of fuel injection does a Mercedes C220 have?
My car has the 38pin diagnostic connector and I connected my “yellow” cable to PIN 4 which is used for the HFM Sequential Multiport Fuel Injection System (HFM-SFI). A few tests to see if everything was working and I quickly began retrieving DTC’s.
What happens when one cylinder is not firing?
When one cylinder is not firing correctly, the engine will become unbalanced, and this can cause heavy vibrations inside your cabin on acceleration or at idle. 4. Check Engine Light Modern cars have great monitoring for all the different car sensors on the engine.
What causes a car engine not to work?
There are a number of possible causes, but you’re going to have to take a good look at your engine to try and diagnose the problem.
Why is my Mercedes C class engine not working?
One Mercedes specialist told be that my cars engine is a gonner and the timing chain and gears were also damaged. Another one told us that our ECU was faulty and then suddenly there was no pressure on the one valve and so the so-called list of difference diagnosis started.

Why does my Mercedes C class run rough off-idle?
21 people found this helpful. Hmmm, so what you’re saying is it idles ruff but passed that part of the test and runs smooth off-idle but fails that part because it’s running too rich ( too much fuel). If you had a vacuum leak at the throttle body you’ll be running lean not rich as you are now.
What should I do if my Mercedes Benz won’t start?
Start the car and you should be able to get around 60 psi. When the engine is running and when you turn off the engine the pressure should stay steady. Always perform this test on a cold engine. Next, make sure that the fuel injector connections are secure and not loose. Check the fuel pump and the fuel pump relay.
When does the engine stall in a Mercedes?
There are never any notifications on the dash or any signs of it beginning to fail. This typically happens when I’m slowing down at an intersection or just driving slower in traffic.
What causes random engine stall, decreasing idle too?
Disconnecting the MAF will set several ECU parameters to a default mode, so it’s effectively bypassing lots of inputs. Thus, even if it runs better it might be one of the other sensors that it is bypassing that is the real issue. So, check codes.
What does it mean when your car is stalling at idle?
Problems with idle speed —things like slow idle, fast idle, rough idle, or stalling after idling for a few seconds—are symptoms that something is wrong with your engine. These should be investigated, diagnosed, and repaired as soon as possible.
