Hi there. This problem is caused by a lack of mobility in your ignition cylinder. The bumps on your key depress a series of channels in the cylinder in the correct combination in order for it to release it's locking...
Thanks for asking. With all of the work that has been done to the vehicle, I would recommend having a mechanic, such as one of our YourMechanic experts, inspect your starting issue. Your symptoms sound like an air/fuel metering concern...
Hi. Your cooling and oil systems would need to be checked for leaks. These are two separate issues. The cooling system should not be getting low, except for a very small amount over a six to twelve month period. The...
The car sitting for a year is most likely a dead battery. These cars are known to have loss of memory problems and the systems have to be reset with a factory scanner. I recommend you have a mechanic like...
This could be a variety of things related to air and fuel delivery to the engine. There are a few things that are common to go bad and cause these types of problems. If the mass airflow sensor which regulates...
There are many things that can cause increased engine noise on acceleration. The crankshaft is at the bottom of the motor and if it were having problems, it would make noise all of the time, not just on acceleration. A...
Yes. Both of these conditions can be true. I know that it is sometimes hard to trust the guy on the other side of the counter. The reality is most of the time a mechanic is not attempting to rip...
More likely mileage and time wore the tensioner out. The tensioner bearing wears out with mileage - it's good to replace the tensioner pulley/bearing when replacing the belt. The tensioner itself is spring-actuated, and the spring can get weak over...
Given you had a "sudden" failure, you might check the crank position sensor first. This component instructs the ignition module when to fire the spark plugs. If the crank position sensor is OK, work your way up the electrical path....
Confirm the basics first: Does it have spark at the plugs? Does it have compression? Are the injectors firing with proper fuel pressure? One (or more) of these is failing you, and will instruct the correct diagnostic path. A trained...
If removing the driver door window switch (or the driver-side console switch), and applying direct power to the harness yields successful operation of the window, the problem is the switch that was removed for the test. This can be confirmed...
Hello, thanks for writing in. I would check the engine oil level and level sensor first as low oil will cause the engine to cut out. If the oil is fine then it sounds like a loose sensor connection. The...
Hey there. Your 190E holds 5.3 quarts or 5 liters. The weight of oil is determined by the average temperature of the climate you live in. If the temperature is above 70 degrees Fahrenheit, I would go with the 10w30,...

If the engine is losing power, the cause of that can be diagnosed, and any required repairs made, if you request an engine loss of power diagnostic. To give you an initial idea, although there are many possibilities, a partial...
You probably broke a throttle cable. It's just a short cable that goes from the accelerator to a complicated looking linkage on the intake manifold. This isn't a common failure so you may want to look hard at the linkage...
Your car uses the old Bosch KE injection system. It is a mechanical, electronic combination system that has the unique ability to run (though not very well) with the electronics not working at all, You might find that the section...
You need to check the lower crankshaft pulley damper to see if it is broken and is not turning with the crankshaft. If it is broke then have the crankshaft pulley damper replaced.
Hello, thank you for writing in. The vehicle's battery will likely be dead. Even if the vehicle has less electronic components sucking battery power, there are some. Even when the vehicle is off and sits, the clock can drain the...
