check your long term fuel trims LTFT with your oft

also log AFR and Commanded AFR

ltft should be below about 8%

afr and commanded afr should follow each other fairly well during accereration

you likely have air leak or over oiled filer and oil got on maf sensor. you can get maf cleaner from auto shop

or you have developed an exhaust leak near or before o2 sensors, did you use new gaskets on header
My LTFT is at 17.18. Is that bad?
