P0159 O2 Sensor Circuit Slow Response
Is this one that is easily handled? I watched a video on YouTube and they checked fuel injectors and the seals and check the O2 Sensor?
Where should I start?

Interesting dilemma, DTC P0159 below specifically mentions 'Front Secondary HO2S (Bank2, Sensor 2) :
Though when you look at the part graphic below, Bank 2 converter only has one #14 O2 sensor indicated; whereas, Bank 1 converter has two #18&19?
Unless APW has there website mixed up? Converter - 2018 Acura MDX 5 Door TECH KA 9AT (acurapartswarehouse.com)
2018 Acura MDX 5 Door TECH was used because your profile generally mentions you have a 2018 MDX.
