Why does my Mercedes 300 have 115 injectors?
For example, older 300 diesels used injectors that were used in the 240 and perhaps the 220 diesel engine (the number 115 sticks in my mind, but I am not certain). This may have been due to the lower fuel quality found in the remote areas of the world, and since the G engine is set up for different torque and rpm demands.
What causes a car to idle rough at idle?
A clogged fuel filter stops the engine from receiving the right amount of fuel causing the engine to be rough idle. Fuel filters are often pretty cheap, and you can easily get the fuel filter removed and replaced from a nearby mechanic or do it yourself if you have some knowledge. 6. Dirty Air Filter
What happens to the engine when left in idling position?
When the engine is left in idling position, it maintains a steady but low rate of revolution approximately 1,000 RPM. The RPM needle stays constant, and this indicates that the vehicle’s engine is receiving the correct amount of air and fuel.
What causes fuel injectors to get clogged with carbon?
Your fuel injectors operate in a very hostile environment, with high temperatures and fuel pressures. The injectors’ spray nozzles have tiny openings, which can get clogged from the carbon that is a byproduct of the combustion process.

What should the rate of revolutions be on an idle engine?
When you start your engine, and just let it run without pressing on the accelerator or putting it into gear, that is idling. A properly idling engine should be able to maintain a steady but low rate of revolutions, somewhere in the vicinity of 1,000 RPM. Your tachometer needle should be steady and not jumping around.
