As far as there being no knock sensor on a 99 2.2 I beg to differ. I have a 99 legacy and just had a diagnostic done and mine is bad. If there is no knock sensor why would it say it was bad and why does Auto Zone, Advanced Auto and my local Subaru dealer sell them. Mine is located under the throttel body and they are rather hard to get to. No offence to who ever said ther is no knock sensor but maby you should recheck your information becuse I know there is a knock sensor since I just changed mine.
