    Any assistance would be useful - my 1987 300 SL has recently started to cut out after a period once the engine has warmed up. It starts up again but then the frequency of it cutting out increases to the point that it is not driveable. At first the concensus was that it was dampness in the distributor cap, possibly due to a crack in it, and it was therefore replaced but it hasn't solved the problem.

    There are no signs of any problems elsewhere, the engine runs smoothly, pressure and temperature both fine. The car has only done 60k miles and runs like new apart from that

    Any pointers would be greatly appreciated.

    Does a 107 have a crank position sensor? If it does its worth looking at this too.
