I bought a 2016 lexus es 350 and I did scanning test and I got 2 engine cods p1604 “ startability fault and p1605 “ rough idling “ is it a problem? How can I fix it ?
Last question: the dealership overfilled the engine oil about 1 L and took the exta oil out after I drive it 2500 km . Do I expect any damages to the engine?
thanks scotty

1 quart more will only burn that extra oil and mess up with your oxygen sensors. DONT USE MOBIL1, they are no longer good, they used to be 20 years ago, not anymore. 1. check your spark plugs, if the look bad, replace them, remove oxygen sensor, if they have oil, replace them with only OEM and only OEM. aftermarket will mess up your computer, remove your oil sensor and clean with soft cloth. check your usermanual and use exact quanity only. give it 1-2 days and check where it is, thats where it should always be.
Do you recommend any oil brand ?
@saeed
Use Penzoil it's did the best in Project Farms head to head oil shoot out.
