I tried the mech's advice, filling almost 3-4 tank fulls from the same vendor (SHELL in blore). and haven't been able to find any difference. in fact its like the car has a mind of it's own, it comes back to normal without much fanfare and goes up all of a sudden too..
anybody with an idea on what could be the problem..
shall try the battery disconnect option once, and post asap...
but in the meanwhile if someone's had this prob, and had managed to get it solved, please do post..
I have faced this problem, each time it was after the service, mainly the 3M throttle body cleaning they use confuses the ECU. Battery disconnection (5-10 mins) has always solved it. But each time one had to pre-set the radio and clock!

Check the throttle cable. Or it could be a case of an erratic cam position sensor?

Interestingly, the same has been noticed on my Ikon after the second free service at 6 months (8000 kms). It did get highly disturbing in between, but less now, or maybe i have adjusted my driving to it.

This is a common phenomenon on my car when I pour in petrol from the pumps that may be filling in inferior quality fuel. The next time you tank her up ensure she's as close to empty as possible and then pour in fuel from a reliable pump. This has been the solution to my santro's engine rpm problems.

suren181 has a point, bad fuel might actually be the problem..

Now I switched from Premium BP / Ordinaary BP fuel to Indian Oil (either premium or non premium) one and RPM problem has almost gone on my Santro Xing! May be useful to other BHPeans.

I too had a similar problem in my Ikon 1.6..
When i release the throttle at 2000rpm, It increases to 3000rpm stays there for 1-2 secs and then goes down... This used to happen as soon as i start the vehicle also. But seems like it has sorted itself out now... Guys any idea why this used to happen??

Default RPM doesn't return to idle soon

My Ikon 1.6 has similar problem. Its very irritating driving in this condition. Have disconnected battery (20mts) to preset ECU, but it did not help. Cable does to seems to be the problem as some have suggested. Will have throttle body cleaned first and if that does not work, will try different fuel. Currently I use regular unladed petrol.

Any help will be appreciated.

iKON issue was reported earlier by someone and it turned out to be some idle adjustment (vacum tube or something, dont remember) under the dash near to foot pedals, 5 mts job.

I had exactly the same experience when I switched from Carb M800 to Santro in 2000 (Advaith Hyundai, Bangalore). The gear shift takes longer in Santro as I have to wait for the revs to drop. Never treated this as a problem, simply assumed it to be normal of MPFI engines.
