Depends on the quality of your retrofit back to stock. You cannot have ANY unmetered air leak in the intake after the MAF. If the MAF unit you are using now is one that the K&N was in front of then clean it using spray, the K&N if over-oiled will let excess oil come off it under vacuum to coat the MAF and then it's messed up. Pull your plugs and see if your mods wet them out to be black or wet (the fuel smell). If so change them. At this point your ebay MAF is not reliable, don't use it.
Any codes or CEL? Then wipe all, you may be in limp mode induced by you messing up your engine tune.
Pray like h-ll that your electrical plug adapting was not more complicated than you thought, often changing a plug up moves some/all of the pins around to not be the ones needed in the places needed and you then toast your computer. You NEVER adapt a plug without 100% knowledge of the exact pinouts of both pieces so that you know where you are at at all times. Accepting others' word for that is death.
