Engine Performance problem
2002 Subaru Forester 4 cyl All Wheel Drive Automatic 89923 miles
When the air is humid /moist the engine knocks for a few minutes then smooths out and runs fine. It only does this after it rains or the humity is high.
I have already replaced the fuel pump and has a fuel injection service. Then I had the Stream O2 sensor replaced.
What else can I have done to correct this problem?
