Hi All,

My 940 is from 1997, B200FT, 2.0L SW with 277000 Km.

About a month ago, I started to hear a ticking sound while accelerating.
Due to the pandemic, I drove the car only 250Km during the winter 2020, I was just driving it 15 min. every week.
However, starting from this summer, I could drive it more frequently, and now I drive it about 300Km/week.

The ticking increases as I accelerate, but it is always there, also on the highway, although not as evident due to the background noise of the car.

For this car, I have always used Castrol Edge Synthetic 5w-30.
Although I only drove 250km with the oil during the pandemic, I have changed it with the hope to get the ticking away, but no go.

As an additional info, since a number of years, when accelerating, the car slightly bogs down, but this never really concerned me because it is mainly at full acceleration, for the rest it drives smoothly, even now that it is ticking.

Distributor and spark cables are brand new.

I never cleaned the injectors, so I was thinking if that could be a possible cause.

As always, any advice is very welcome.

Thank you!
Alex
