The early 300 SL suffered from dodgy HT leads and spark plugs if not regularly maintained, the problem with Mercedes Benz though is that the cars have so many features that it is almost impossible to diagnose without seeing the car. Some things to try (in this order) are : - Spark plugs, Ht leads, remove and clean Distributer Cap, replacement of HFM sensor (common fault), if none of these help then faults have been known in throttle valves and fuel pumps/filters

Happy fault finding

Hi, i have had the same problem with my 1993 SL, however i couldnt drive mine at all when it started to misfire. I replaced the distributor cap, rotor and ingnition coil which sorted the problem - the misfiring etc does seem like a fuel problem but it is actually an ignition issue. You could try starting with the sprk plugs 1st and work round that way, but water in distributor cap is common on this age of car.

Engine overheating after driving for like 20 miles or so

Yes a stopped up catalytic converter can make it run hotter . Something else to look at is air in top of motor, Some cars have a bleeder valve to let air out . If not loosen the highest holes clamp to let air seep out , if coolant comes out look at other things such as timing ,stopped up radiator, to much fuel.

We have a Subaru Legacy GT, Twin Turbo 93, the car cut out and will not start, no fault codes, replaced spark plugs, fuel filter, checked the fuel pump, replaced air flow meter, engine temperature sensor,...

sounds like your timing may be off, or have a crank shaft postion sensor failing, when it cuts are you losing spark completely? do you have a fuel pressue gauge? whats the pressure? also you could try running it with the map sensor unplugged and see if the condition improves

Mercedes e230 1998. cold starting.

Mercedes has a cold start valve to spray extra fuel to assist the ignition when the temperature is cold. This is the problem with the cold start valve is not opened when it needed. There are 2 possible causes: 1- The valve is bad. 2- The coolant temperature sensor is bad.
The valve part is expensive and labor is not cheap. The first economic way to address is to replace the coolant temperature sensor. This sensor gives a different resistance reading as temperature changed. When it is bad, it give an erratic reading at cold temperature so the ECM could not recognize to give a signal to open the Cold start valve.

Hesitation , skipping,engine cuts out when accelerating

Im having the same issue I believe. I have a 94\' Chevy 1500 and when i accelerate it will jerk like the gas has cut out but it wont stall. It just jerks and slows me down. It only seems to do it when going up a hill. I feel like it could be the fuel pump or possibly some intake gaskets?
