Hi, I've got problem with my Saab(B202, '90).
The engine is knocking. When I accelerate hard It starts at about 2500rpm and after 4000rpm it's ok again. When I don't accelerate (only drive at certain speed) it knocks all the time. When it's cold you can hardly hear it, but after 10km there is no way to miss it.
Hmm... I don't know how to describe the sound
It's the same sound as the engine knocks for about 2sec after it starts (maybe only my engine does it).
There's no problem with oil pressure.
Thanks for any ideas.
