Mike-in-Ohio Posted December 29, 2005 Share Posted December 29, 2005 I just replaced my Timing Belt on my 1999 Subaru Outback Sport 2.2l engine (104K). Idle is good about 500 rpm, however the car hesitates when I begin to move. Then works well at speeds, and at 2000 rpm, however, around 2500 to 3000 rpm the call begins to boggs down unless I lift off the gas. Yes the check engine light is on, however it was on before I made this change and is related to an O2 sensor. Any suggestions? Btw: the car hesitated before the change, however was not as bad as it is now. Mike Quote Link to comment Share on other sites More sharing options...
blitz Posted December 29, 2005 Share Posted December 29, 2005 More specifically, is it a "O2 sensor slow", or a "sensor out of range"? Also, what kind of tranny? Quote Link to comment Share on other sites More sharing options...
Mike-in-Ohio Posted December 29, 2005 Author Share Posted December 29, 2005 Manual Transmission. i've replaced the Fuel Filter and drove it to the local Auto parts store and used their computer. the 2 error codes are as follows: P0141 O2 Sensor heater Circuit Malfunction (Bank 1 Sensor 2) (i've ordered it and should be in tomorrow) P0325 Knock Sensor 1 Circuit Malfuntion Bank 1 or 1 Sensor the car will not "chug" if i increase the speed very slowly, ie. ease the gas pedal. So i'm thinking Gas not timing. thanks, mike Quote Link to comment Share on other sites More sharing options...
