i have a 99 legacy 2.2. from idel to around 2200 rpm the car bogs, replaced mas air, tps, air idel control, fuel filter, cats, and it's always maintanced, im at a loss and can not figure it out

Check your Icp valve (igition control) to check timing, check the conductivity on your ICM (ignition control module) and lastly, you may just need a new cap and rotor for your distributor, common problems with bogging. Other than that you might have bad injectors letting too much gas in, a bad air filter, ect.... try it all out and contact me if you need further help

ive tried all that yesterday, and still no luck

Check your vacuum lines near your intake. Usually with bogging in gears would be a bad front o2 sensor.

ya i did vacuum and 02 was my last guess

well that could be the only things bogging it down unless you have a clog or bad fuel pressure because of a worn out fuel pump. other than that im stumped

What brand of spark plugs are you using ? NGK or Denso are both acceptable.Traditional US brands such as Champion, AC Delco or even BOSCH (German) brands are questionable.

could also be a clogged cat converter.
