DIY Crankshaft Position Sensor BenzCranks No Start
Problems with the Crankshaft Position Sensor (CPS) on Mercedes-Benz cars are fairly common. If you have been experiencing stalling or no start conditions, a failed crankshaft position sensor is often the problem. Your CPS may have failed if the engine cranks but it will not start. At first, you may experience no start conditions intermittently. As the crankshaft position sensor fails completely, the car will no longer start or will die when you are driving. Starting problems are initially random, but more frequent when the engine is hot. Other symptoms of a failed crankshaft position sensor are poor acceleration, engine vibrations, poor throttle response, bad fuel economy, hesitation, engine stalls. The engine starts if you let it cool down. (Thanks to MB Medic)

The only thing that comes to mind is the catalytic convertor in the exhaust system.It can become restricted,reducing flow in the exhaust system,which also reduces engine power.These convertors run at fairly hot temperatures,and the extreme heat and conditions aggravated,or overloaded it.It's not very expensive to have it checked at a reputable muffler shop.I have seen extreme instances where this caused parts of the exhaust system to turn red,glowing hot.

your camshaft position sensor may be going bad. usually with an old car it tend to go bad. The top of sensor can be covered or gumed up with grease, oil, dirt and cause it not to detect the flywheel turning. Camshaft sensor send single to your DME to deliver fuel and sparks to you engine. If camshaft sensor goes bad it will seem like your fuel pump and ignition coil is bad even-though they are good. Faulty camshaft sensor may caused you to have this issue and problems such as sometime it run good and all of sudden it shut off, sometime its start good and others time is doesn't start. Once the sensor goes bad, the car will not run. There are two Sensor one for the fuel and one for the sparks, I would replace both sensor because soon or later if it will go bad, it will leave you stranded although if you replace one you might as well replace the other. Check the coil and test using the light or volts tester to see you getting power to the coil, next check if your fuel pump is working, fuel pump will not stay running unless the sensor sense the flywheel is turning from your camshaft sensor. next time when your car does not start, check if you getting spark and fuel. Both sensor will cost you around 130 bucks. assuming your DME, fuel pump, coil, wires, etc... is working. keep me update and I will try to walk you through. btw stop by at any auto part store and pick yourself up Haynes auto repair book for your car, its a great tools and investment to have for your next repair work if you plan to keep your car and get to know the heart of it. good luck and i hope that help some.

Sounds like you have a small bit of dirt or grit in the fuel system when accelerating it is drawn with enough force to cut off the fuel supply then is released when engine at Idle.
1 run liquid fuel line/injector cleaner in 1 tank
2 check fuel lines for debris
3 change fuel filters
4 have fuel tank flushed
here is trouble shooting order less expense to greater.

try changing the fluids and filter in tranny thats about the mileage for changing filter and fluids anyway so its called for so its not a waste

Have a problem with my A/C. was leaking not holding proper charge. When that happens the Eoconomy light comes on and can't turn it off until system is prpoerly charged. Is their a reset on this system to turn that off once the proplem is corrected?
