Nope, you shouldn't. Use NASA Carb Cleaner costs around 270 rupees, I bought one from Filter House, montegomery road. Dunno where else they are available. Open the throttle body, use some petrol to clean it. Let the petrol evaporate, spray the cleaner well on the moving parts, the clean the sensors aswell.. dont pour the spray into them just clean them gently with a cloth and the cleaner.
Put the throttle body back. Start the car up, you should already feel some change..
Now, spray the cleaner inside the throttle body, of course the air filter won't be connected, and also your engine shouldn't be too warm. To do this, you have keep your revs high around 2 to 3K. Once you'll start spraying in, the engine will bog down and shut off, don't let it do that, rev more if it bogs down, donot spray constantly, just a few 3 to 4 second long sprays after a few seconds, do this 2 or three times, and keep the car started, you'll see white kinda smoke coming out of the exhaust pipe, donot panic, cause that would be normal. Now you keep the engine at constant revs for a few more seconds, till it stabilizes itself, and the white smoke finishes.. then put the air cleaner pipe back on and you're done.
