boatrick1234 Posted October 28, 2011 Share Posted October 28, 2011 (edited) hello everyone. my wife has a 1996 legacy 2.2 postal for her mail route. it keeps losing power mostly when she is climbing a hill on her routes. it doesnt miss or die it just powers out like she took her foot off the gas. there is no check engine light on, no miss or anything but the power loss. i have changed the plugs, the wires twice, the enjectors.fuel filter, fuel pump twice, and air filter. i also had the exhaust and catalytic convertors checked and it was all in good shape,no blockage . i'm at a total loss. does anyone have a clue? thank you all Edited October 28, 2011 by boatrick1234 Link to comment Share on other sites More sharing options...
davebugs Posted October 28, 2011 Share Posted October 28, 2011 I'd probably star twith knock sensor. Link to comment Share on other sites More sharing options...
Durania Posted October 28, 2011 Share Posted October 28, 2011 Knock sensor would be a good place to start. Make sure when putting the new one on, don't overtorque the dickens out of it and clean the mating surface. Link to comment Share on other sites More sharing options...
Fairtax4me Posted October 28, 2011 Share Posted October 28, 2011 Check simple stuff first. Vacuum hoses, PCV and breather hoses, air inlet tube clamps. The knock sensor can cause power loss, but the other stuff is easy to check and much cheaper to start with. Once you clear that the knock sensor is fairly easy to replace.
