R129 500 intermittent engine hesitation

[dellyend1]

Dear All,

Firstly hello I've just picked up my SL500 1993 and driven back a 110 miles which was a joy. The car is great, other for one small concern.

After I have driven approx. 50 miles , the engine started intermittently hesitating ( a bit like bad fuel going through the system) . It would then disappear for 2o mins and then happen again. If I booted the accelerator it did not misfire but just lurched into life.

I initially thought it might just be crap in the fuel as the car has been standing around for the winter or maybe some crud in the filter. Failing that I am thinking HT leads which after an hours driving are producing a small misfire ?

Any help would be gratefully received.

Many Thanks

Jeremy

Probably distributor caps and rotor arms, may be worn out or just full of moisture.

Did you put fresh fuel in it? How long had if been standing?
