Changed Spark Plugs Now CEL on and Cruise flashing (SUBARU)

I have a 2006 Subaru Impreza 2.5i wagon with a manual
transmission. changed the spark plugs since the car was
having some rougher starts lately, i pulled out two brands
of plugs, with two different gaps. a little bit of oil on 2 of
them. i put new ngk platinum plugs in and forgot to plug in
mafs so it didnt start first try but started right up second
try. was running weird, realized mafs was unplugged.
plugged back in, CEL still on and cruise still flashing
aswell.
