Question about 1994 Mercedes-Benz C-Class

1 Answer

My 94' C 220 has 300,000 miles and recently it was making a sound like a vacuum cleaner and I lost acceleration completely. It started smoking and I pulled off the road. It hasn't started since. What happened?

Would a faulty egr valve on my 02 PT Cruiser 2.2crd cause excessive black smoke and injector knock under full throttle....thanks


black smoke is over fueling and although the turbo appears to spin ok the vale variation actuator may not be operating correctly
there are vanes in the exhaust turbine housing that are altered to increase the exhaust gas flow onto the turbine blades for quicker acceleration and these vanes are operated by a vacuum actuator and rod by a sensor
the vanes are subject to extreme heat and can rust stuck open or the hose gets hard and cracks
s not allowing the vanes to work
I would be concentrating in this area before the EGR valve
run the fault codes as well to get a better idea of the possible fault as some systems only put the light on for extreme conditions in engine and transmission

I have a 2004 ford excursion with 233,000 miles it makes a load humming noise when it idles but when you give it gas it stops. Sounds almost like air leak some where did replace the ERG valve recent.


There is a rubber vacuum elbow behind the intake plenum of the engine. After awhile, the rubber vacuum boot tends to collapse on itself (cavitates) and makes weird funny noises at idle when engine vacuum is the greatest. But you won't hear it when yo begin to accelerate. Common problem with these vacuum hoses. Verify that the hose is the problem and the dealership carries plenty of these replacements.

My 94 Toyota Camry 4 cyl is running really rough and stalling out once the engine warms up


Get rid of cold air intake and re install stock also sounds like your mass air flow unit is going out or your cars ecm isnt operating properly check air filter make sure its not clogged up then check all your vacuum hoses for cracks,dry rot or kinks making sure none are pinched causing vacuum to not respond.ok after this check the fumes from exhaust for color but it could also be catalytic converter even though it says air temp.when this problem occurs it can be number of things spray electric cleaner on wires as well and check for loose wires now take your time going over these things to be sure you accurately inspect this

When cold start works fine but when driving for half hour and a/c is on when making a stop engine starts to stall and accelerates and goes off completely


Idle air control clean it with Mass air flow cleaner or carburator cleaner and dont forget you need to do the throttle body also listen for any vacuum hose leaks

BLUE SMOKE FROM AUDI RS6 ON DE ACCELERATION AND START UP THINK OIL STEM SEALS ARE LETTING OIL THROUGH. CAR RUNS FINE I THINK, AND EXCESSIVE BUILD UP OF OIL IN DRIVER SIDE TURBO PIPE, 62000 MILES WITH A...


General rules of thumb: Low speed engine on acceleration with smoke in the exhaust plume = worn piston rings High speed engine accelerating (spooled up turbo) with smoke = oil form turbo bearing and/or piston rings Engine on over run (coasting down, foot off the gas) with smoke = oil from valve guides. VW/Audi make good engines with tight tolerances so none of the above should apply at 62K miles; just make sure that the oil (the right oil) and oil filter are changed regularly.

It's the automatic choke!

The choke is "closed" or barely open... When cold, the engine needs a RICH mixture (more gasoline, less air). When the engine warms up, it requires a LEAN mixture (less gas, more air).

It is probably creating BLACK tailpipe smoke ... that means unburnt gasoline. (Blue smoke is OIL, white smoke is WATER).

Put the parking / emergency brake ON.
1. Remove air cleaner assembly from intake, use a carb cleaner spray or throttle body spray cleaner and spray just a little. (AutoZone $5)
2. Find the accelerator2.gif arm under the hood.
3. start car, rev the engine to make sure how to operate the accelerator from under the hood.
4. Carefully spray into carb / throttle body and work the accelerator ... don't let the engine die...
5. Watch out for "backfire"... it may create a small flame out of the carb. It will extinguish itself in one second.

6. You may need to do this two, three times.
7. Add a "complete fuel system2.gif cleaner" to your next tank of gas ($8).

That's it! ... pretty cheap, too.

Hope this helps!

White smoke from exhaust


Hello;
The white smoke is from coolant entering the combustion chamber(s). Coolant can enter through the water passages sealed bu the head gasket. You have probably blown a head gasket. You should check your coolant level. You may have acracked head if you continue to drive it and overheat. The temp gauge only reads when exposed to coolant, not air. Take out thhe spark plugs and look them over. A white glossy apperance will indicate water in the combustion chamber. You may need to surface the head once you have it removed so that it is flat. Hope this helps.
Thanks;

Rattling sound 0-20 mph comes and goes, 6 disc cd changer skips


Howdy,
the rattling sounds like its the hydrolic lifters (tappets or cam followers called also) not really a hard job just a pain cause you've to strip the engine to pieces to do. Its very time consuming so unless you've some experience i'd place this in the hands of an experienced mechanic. This should also stop the smoke problem.

The engine service light is on a timer from service to service so thats nothing to do with it.

The cd player your right about it just need the lazer llens cleaned. You can buy a cd cleaner kit for cheap in any music/record store.

Hope this helps if not let me know and I'll try and find the solution

Cheers
