Babupaul,
How many kms has your car done? If it is not much then you need to wait for the engine to free up before the average improves... in any case, it is not *too* bad, do get the car checked at a MASS though.
My 2001 Esteem (MPFI) with 82Kkm on the odo gives me 12 - 13Kmpl in the city without the AC and around 17 cruising on the highway at 80Kmph... she never gave me 21 ever! We also have a '96 carb Esteem in the family that gives 11Kmpl in the city and about 13Kmpl on the highway (without A/C).
You should also be aware the the MPFI Esteem has taller gearing than the carb version, esp. 4th and 5th gear... you may need to drop 1 gear lower to get the same "oomph" in acceleration as the carb version while overtaking on the highway... not really a problem once you get used to it.
The high idling thing... aah... that's a quirk with MPFI Esteems (at least BS-II) and I think many other MPFI Marutis. If you have time, just let the car warm up (while idling, dont touch the accelerator) for a minute or 2 (till the temp. gauge reaches the "C" mark) ... then drive normally. If you dont have time to wait for the engine to warm, then u can drive off immediately, but try not to use the accelerator till the temp gauge reaches the "C" mark... easier said than done! ... ok, if u used the accelerator before the engine got warm, the ECU will be confused and keep revving the engine; but dont worry, the next time you stop and let it idle (without accelerator) for 5 - 10 seconds, the RPM will drop to normal values... if you dont want to wait even 10 seconds when you stop; switch off the engine and restart... RPM will be normal.
Welcome to the quirks of the Esteem ECM!
