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

Steve thanks for the quick response!
I replaced the gaskets all around. Checked for exhaust leaks by way of having someone cover exhaust and didn't see any leaks (I realize it's not the most effective way)
Ltft fluctuates between -2.34/-3.12
AFR and Command AFR seem to follow almost identically. Parameters based on another thread seem about right. However at wot it does read11.25:1
My buddy next door said I may have over oiled as well, but it didn't "appear" to be over oiled.
