Salam All,
I hope you guys are doing good. My corolla rpm are slightly on higher side. Noone opened the throttle body, noone manipulated the rpms itself. Without AC and headlights off, it is near to 1000 whereas it used to be 900. Anyhow the difference is not that much. Actually to kill the issue and to bring it to the factory setting Im trying to reset the ECU. Can someone out here can guide me how to do it. I have removed the negative terminal for sometime, I think for an hour and reconnected but it didnto reset it. Car started normally and all the gadgets worked normally.
