Hi Saahilsh,
For the age and mileage of the engine, oil consumption can occur due to worn valve seals.
For engine to surge, it is usually due to excessive air getting past the throttle body and possible causes are leaking vacumns. The other item to cause surging would be the Idle Air Control valve. It could be stuck in the open position and when that occurs, excessive gets past the throttle bodt.
Check the coolant level and the hoses to and out of the IAC. Insufficient coolant or clogged coolant hoses are possible causes.
