I have a 2008 WagonR that has run 48000 km. There is a clatter noise from the engine on slight acceleration which is present only during running. But at the same time when I depress the clutch and accelerate the sound is not present. MASS isn’t able to identify the source. Will Throttle body and injector cleaning solve the problem? The Mileage and performance of the car is not affected. I have used IFTEX system G since past 500kms and the clatter has reduced to some extent but is still present.
