Hello Everyone!!!
I have a 2004 Se Saloon (1600cc). My car's engine is bubbling at idle, recently I had the car tuned with throttle body was cleaned etc but the problem still persists. There is also a slight grinding noise from the engine when it goes above 2500 rpm. The engine sound at start up is also different than before, can anyone please suggest a solution?
The car is very heavy on fuel (8 Km/l max), and the acceleration seems slower than normal.
The cars engine does not blow nor does it decrease or burn lubricant, the engine oil is changed consistently at around 2500-3000 km. The car has been inspected by technicians at toyota and they suggested Hi Octane Fuel since then I have been using a tank full of Hi Octane once a month, but the problem persists.
I would be grateful if someone can suggest a possible solution
Thanks
