I was driving to work a few minutes ago, when coming down the freeway
the car made a sound like an explotion, a fellow of mine who was behind told me he saw like a little flash-fire.
The car did the same sound 3 times.
This was a short trip no more than 13 km
I was driving at 100 km/p/h i was in 3rd gear down hill when the explotion became.
---on saturday i went to the mechanic and he Ędid a tune up, valve adjustment and he adjusted the distributor which was with a weird sound from a few days ago.
gimme a clue please on what is the origin of the sound-explotion.
Car is an E30, 320i european version, 09/84 production date model 1985.
