Technology wows and also make us feel helpless. More so when the problem is as unique as teh RPM needle of the car misbehaving.
My Hyundai i20 Sportz seems to be misbehaving lately. Once I release the clutch after changing gears, the RPM needle shoots upto 2000. Surprising that even when the throttle is not pressed why should the RPM shoot. Can you solve this mystery?
As you must be aware all cars on road today are technologically quite advanced. Most of the cars functionality are sensors controlled. Any malfunctioning sensor can therefore cause erratic behaviour in a very well functioning car
Specifically in your case idle speed sensor that might require some ckeck-up. Nothing major, but it might not be a bad idea to get it checked at any Hyundai authorised workshop closest to you. We are sure that they will probably tune-up and do the necessary cleaning after which you will be good to go.
