Dear BHPians ,
I faced a strange problem in my i20 (petrol) today.

I was travelling at the speed of 70,2K RPM when suddenly I realized that that on pressing the accelerator the car is not moving forward. I released & pressed again but car seemed to be dead. The RPM started dropping (From 2K) ,I could not understand what has happened, I down shifted & switched off the AC & the blower but this also dint helped. I even switched off the stereo but to no avail.

Slowly I moved the car to the left most lane gradually downshifted to 2nd gear, continued for some time & then the car behaved normal. Although it was highway but the road was empty so it was not very scary but surely something to worry about.

I stopped to see if there was any white smoke but there wasn’t any.Engine temperature was also normal

Just before this happened I had put the blower speed to 3 since it was quite hot in late afternoon can this be a problem?
After some 30 mins while moving in traffic in 2nd gear I noticed the battery sign fluctuating just for a second. After this I travelled almost 80Kms but dint faced any problem

I would be visiting the service centre tomorrow but still would like to learn what could be the possible causes?

I read some similar threads for Swift & Vista but they were deisels,the one being questioned is petrol & only 3 months old ,1500 Kms driven

Most likely a case of bad fuel. Go through this thread to know trusted petrol pumps in pune. http://www.team-bhp.com/forum/shifti...rol-pumps.html

Looks like it is a problem with the Throttle sensor or the feedback from this sensor to ecu

Hook up the car to a scanner to find out(that's eactly what you're planning,right?)

Just to add,switching off the stereo will make no difference in any scenario,except if someone wants to speak to you.

Did the "check engine" light, 'light up' during this problem??

[ph03n!x]

Umm... did you try cutting the gear down from (I assume) 5th to 4th / 3rd and see if the RPM goes beyond 2k? Wanted to check if it is with the engine RPM being "locked" at 'x' RPM or something else...

Was there any engine warning light at the time?

might be some sensor issue.

The service centre tried it but there was no problem.They just said it could be a problem with the fuel.For them this is a new problem ,havnt heard of it before

No there was no check engine light lighting up.

Yes I downshifted to 4th at same speed but the RPM dint increased,dint tried at 3rd gear,gradully lowered the speed,came down to 2nd gear & continued with this for some time.It worked this way

Since this was the first time I faced this issue,I'm willing to believe that it could be due some adultrated petrol.
Will keep everyone posted if this arises again (God forbid ! )

I may be stupid but was the hand brake on?

If they still have'nt, ask them to thoroughly check the alternator.

Could be something simpler : Did you downshift? . If you were in too high a gear at 70 kph, and needed to suddenly accelerate, downshifting to a lower gear in the i20 is mandatory. That 1.2 L really has limited punch.

You can go the service station and get everything checked, but my sense is there is no real problem. I faced similar issue in my Ikon. The cause was bad fuel. Topped up at a known petrol pump, got the fuel tank cleaned up at the service station and the car was good to go. Didnt see the issue again.
