Just pull the VIOLET 3 amp fuse as this is KAM, and this will make the ecu relearn.
I would in any event clean the MAF with carb cleaner, it will not hurt, especially if it has a oiled air filter such as K&N etc, the oil contaminates the wires in the maf.
If it is still the same clean the ISCV, AND check for air leaks.
