Hallo to all. New in your site.
I have a 89 300SE which in general give me no problem.
However, occationally the engine just die, as if out of fuel.
This have happened several times the last year.
I have changed the fuel filter & pump twice, the kick-down rele three times, installed new cables from kick-down rele to pump, but the problem always return after a week, or two months, (I never know). (Sparkplugs, cables and distr. cap is new).
I have also noticed that when driving at a higher constant speed, (160 to 180 km/h), and releasing the throttle followed by full throttle, the engine just die. Have to "jiggle" the throttle repeatlly to get it going again, as if the throttle "valve" in the intake get stuck in full open position, (booging, as on a Q-jet).
At the moment the car is parked on the high-way after my wife had a break-down. (She is not happy

).
Thanks, Per.
