MatteLegacy25 Posted October 6, 2014 Share Posted October 6, 2014 I'm having issues with my legacy. No check engine light on but its got a lot of lag. I can put it to the floor and it just bogs down and won't get up and go. Kind of chugs a little bit. if im in first gear and get after it seems ok to a point. Any suggestions on what the problem might be? Turbo? plugged cat? misfiring cylinders? Link to comment Share on other sites More sharing options...

My guess is that your turbo is on its way out. Has it been replaced before? Link to comment Share on other sites More sharing options...
MatteLegacy25 Posted October 7, 2014 Author Share Posted October 7, 2014 I've got a cat back exhaust and a k&n air intake on it. And yes the turbo has been replaced before. The whole motor has actually been rebuilt about 3 years ago and I believe they put a mittsubishi turbo in it because they said the bearings were better or something. Just started giving me issues a few months ago. Link to comment Share on other sites More sharing options...

ragman Posted October 9, 2014 Share Posted October 9, 2014 If you have an aftermarket turbo, a catback, and a cold air intake....all on the stock tune, could be quite possible your IAM is below 1, which pulls timing and makes it run like its in safe mode. Basically, you need to run a tune with those aftermarket parts. Link to comment Share on other sites More sharing options...
MatteLegacy25 Posted October 10, 2014 Author Share Posted October 10, 2014 Cleaned the o2 sensor and that made a huge difference! Woke the car up big time. Link to comment Share on other sites More sharing options...
