Question hesitation during acceleration

What can be done about hesitation during/under acceleration? It does it in all gears.

What MY? Is it only after a recent oil change? Do you have mods?

I have heard that air in the oil filter will confuse the knock sensor and cause ignition retard. Search www.imprezars.com for "gary" if you think that is it and you will find "gary's fix" there somewhere.

I also know a few people who fixed it with a panel air filter like AMSOIL or K&N. I sell AMSOIL filter at my cost (after paypal charges and shipping direct from AMSOIL, I make $0.49). I have a buy now button on my website.

Try the ECU reset first.
It helped me after the same problem.

Especially if you have recently done any mods, I would do the ECU reset too and see what happens.
I've noticed mine seems to hesitate a little, but only with the AC or heat on, so I've never worried, but nearly every car I've ever driven (with the exception of those that cost over 50,000) has a little hesitation with the compresser running.
