thank you guys for you replies.
yes the yellow light showed at 478kms(+-) and i drove 10 more kms after that.. but i am confused that how come i put in 46litres of fuel :s i am still puzzled about that...
after that i thought its not okay because 4500rs worth of petrol is too much and i need to get things sorted..so i went to a mechanic and then asked him to do something so that the mileage improves.. i have gone to him before..
he asked me to turn on the car and then he accelerated it and then he said switch it off.. then he opened everything and reached to the tappets... i asked him why did he do that? so he told me that that tappets needs to be adjusted and the adjusted them to 8 number.. basically the tappets were at 12 number before.. and since he has done his work the sound of the car has vanished.. and its like quiet.. i can only hear the alternator a little other than that the car is quite mashAllah..
i asked him that is the throttle body okay or not? he said no its okay and does not require cleaning or anything.. after all of this he was asking for 600rs i said i'll give 400rs but then finally he took 500rs..
the mechanic also checked the plugs and they were red... he said the engine is ok Alhamdullilah and everything is fine.. so lets see what happens now.
now the pick of the car has also improved and also the idiling but i am not sure about the average so i am planning to fill the tank again when i have done 100kms is that a good idea?
after everything he reset the cpu of the car... i don't know why did he do that.. maybe you guys can tell me...
@fahad. brother thanks for the help and your suggestions i am definitely going to check all of these.. i drive slow and avoid hard braking unless necessary.
