you need to always state year/make/model/mileage/engine size
And if you listed the brand & part number of the plugs I coud verify it was in fact the right plugs.
some toyota's spec a dual prong plug. NOT using that can cause this.
Usually it's the v6 and some v8 motors that require it.
a car computer would not have to adjust to spark plugs. However if you disconnected the battery it could take up to an hour for the drivability to return.
