Question about 1993 Mercedes-Benz Mercedes Benz Sl Class
The car starts fine from cold, but when it gets up to running temperature it starts to miss fire cuts out on tick over then unable to start it again until it cools down,but if you drive the car not letting the car cut out, it will eventually clear and the car wiil be fine, but if not used for a few days the problem starts all over again ??.
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.
