you need to have a tune done for it all to work.

Those headers shouldn't make a MAF code come up. Fueling may be a little off but it should not affect idle at all unless you have a pretty big exhaust leak. The K&N may have oiled up the MAF sensor. I would start by making sure you don't have any leaks in the intake path and to carefully spray the MAF sensor with a cleaner made for that.

You'd be best to have a mechanical gauge check of your oil pressure. Just because it has the correct level of oil doesn't mean it is being pumped to minimum pressure. It could also be the oil sending unit is going bad and the mechanical gauge check will verify if it is.
