The major problem which i am facing is that when i start my car in morning it gives me average pickup n ac works fine but in afternoon when temperature goes 40c plus then the car performs very very bad. When i try to accelerate it a goggle type sound comes or u may say it knocking comes and car takes jerk n engine goes off or sometime if engine does not goes off then goggle sound comes only n we have to accelerate very slowly slowly.and loss of power is there
I have changed its radiator coolant get it washed properly, fuel injection system also cleared, oil,oil fiter,air filter,as wel as high octane is also poured in fuel tank.even i got the manifold checked and its clear now wat!????
And fuel avg is also very bad at long it gives 12km/ltr
Plz guide my as im in great tension
