It looks like either an ignition problem with number 1 cylinder or a leaking fuel injector in the same cylinder.
The air filter was the 1st step and that didn't fix it. Next you should replace that spark plug.
Next step would be to swap the coil with the one on the number 2 cylinder and see if the fault changes to cylinder 2 misfire followed by swapping the fuel injector the same way.
Last guess would be mechanical problems with that cylinder. Do a compression test to check that.
