On my Hyundai Accent 2012 1.6L engine, high RPM is 1500 in the morning and I rarely have time to see if it will adjust but when I put the AC ON and Drive, RPM is 1000 and also acceleration is sticky but when I'm about to apply brake it jerks like is about to speed up.

then in the afternoon under hot sun RPM is below 800, idling is not steady going up and doing and also vibrate with Ac ON


Only error code is P0030 and that's H02S bank 1 sensor1


Good morning sir, please help me
