Suzuki hustler issues

My Suzuki hustler 2015 turbo is running lean with long trim around 15 and short trim around 10

Plus my maf sensor is always gets coated in oil. When I clean the MAF. After a few days the MAF is covered in oil again.

Please can anyone guide me what can the cause of high short and long fuel trim and what causes MAF to get covered in oil.

Can't figure the cause of the problems.

seems like PCV valve is choked and needs cleaning

What oil grade are you using? Check PCV valve and the breather hose.

i m not a pro but i think O2 sensor should be checked as well.

There could be sludge in engine as well.
