Dear Experts, is there a specific way to reset the ECU, i have done it twice by disconnecting the -ve terminal of the battery and car is idling at around 600 RPM which is causing it to rattle.
I just press the paddle to minimum possible extent (taking IDLE RPM to 700-800) and its smooth as silk. Also its doing knocking like mad.
too much knocking since the ECU reset.
Please advice the solution.
Dont intend to get it opened up from a mechanic considering it all started because of me (ECU reset attempt) which i am not sure whether it was required or not.
