Vehicle rpm rising automatically?

My indica v2's rpm rising automatically in idling. I already overhaul the FIP and injector for the same problem. But its now remain the same. Pls help me

I know nothing about that specific vehicle but in a normal automobile gasoline engine, restricting the air flow to the carburetor (choking) will increase the idling speed. A clogged air filter, air intake or a sticky choke that doesn't release when it's warmed up will all produce those symptoms.

Thankyou.. But my vehicle is diesel engine.. There is no carburettor.. Now I think this may happen due to choking in the throttle body r tb sensor problem..
Check the throttle body. That may defect over time and cause the RPM to rise without reason.
