Lawsonmh15 Posted May 7, 2005 Share Posted May 7, 2005 I recently purchased a 99 Legacy SUS Limited and feel as though it is running a little rich. On my 78 k1500 I just adjusted the screw, that won't happen here I don't think. So; is there a way, without a programmer, to adjust the mixture? If not, is there anyone is south denver willing to take some cash for helping me tune this in? TIA. Link to comment Share on other sites More sharing options...
mattocs Posted May 7, 2005 Share Posted May 7, 2005 disconnect the battery for half an hour, and then hook it up, and let the car idle for 10 minutes. This resets some stuff...its worth a shot :-/ Any check engine lights on? That may be causing it to run rich... Link to comment Share on other sites More sharing options...
Commuter Posted May 7, 2005 Share Posted May 7, 2005 The 2.5L DOHC Phase I engine is known for running rich. I don't think there is anything you can do to adjust, since it is all computer controlled these days. That is, short of getting into the programming. You might want to try changing the O2 sensor. As they age, they will cause the mixture to go even richer still. I noticed a difference after changing mine. It was not thowing any codes, but the dealer did say that it was working a little "slow". (Fewer cycles per minute than is the norm.) Commuter Link to comment Share on other sites More sharing options...

Also, I just got the oil changed about a half an hour ago and noticed that they listed the engine as a 2.2. Being that I live 1/4 mile away I came home and am letting it sit for a bit to see if they got enough oil in. It seems as though there seems to be alot of confusion about these SUS'. Is it an outback, legacy, 30th ann. etc... Anyhow... Any tips to CHEAPLY squeeze a few more lb's of torque out of this thing would be greatly appreciated. Thanks again for the expeditious responses.
