gordy07 Posted March 2, 2009 Share Posted March 2, 2009 My mate has a 53 plate UK impreza turbo,about two weeks ago he fitted a full exhaust system and yesterday his engine warning/management light came on.Any ideas? I though it could be something to do with the o2 sensor but he says it has been refitted properly to the new system. Any help greatly app. as always:) Quote Link to comment Share on other sites More sharing options...

gordy07 Posted March 2, 2009 Author Share Posted March 2, 2009 I dont think so david,it must be a common thing though because theres not many subarus out there with standard exhausts Quote Link to comment Share on other sites More sharing options...
dan4 Posted March 3, 2009 Share Posted March 3, 2009 air mass reading incorrect due to split intake pipe? overboost due to exhaust and cold weather? Quote Link to comment Share on other sites More sharing options...
gordy07 Posted March 3, 2009 Author Share Posted March 3, 2009 It turns out its a fault code because of excess gases not being removed by the cats. He has been advised to either put the cats back in or remap the ecu at a cost of £650:blink: Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted March 3, 2009 Share Posted March 3, 2009 Cant he just live with the light, does it affect performance? Quote Link to comment Share on other sites More sharing options...

Pig Posted March 3, 2009 Share Posted March 3, 2009 Very common on a scooby. You can turn the light out but it will come on again in no time. Quote Link to comment Share on other sites More sharing options...
gordy07 Posted March 3, 2009 Author Share Posted March 3, 2009 He is one of those guys that if he knows there is a problem making the light come on,then he wont just disconnect it:blink: The performance is much more responsive at lower revs:D But when he accelerates and dips the clutch to change up a gear the revs hold for a second before dropping:( And his fuel consumption has gone through the roof:taped: It seems to be running lean and probablly does need re mapped tbh Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted March 3, 2009 Share Posted March 3, 2009 Running lean and excessive fuel consumption are opposites. Theres his answer Gordy, remap, or return to stock. Or just man up and ignore it Quote Link to comment Share on other sites More sharing options...
DannyB Posted March 3, 2009 Share Posted March 3, 2009 Remap asap! Dont want to go and kill it now do we.... Quote Link to comment Share on other sites More sharing options...
gordy07 Posted March 3, 2009 Author Share Posted March 3, 2009 Thanks for the input guys i will try to convince him to remap tommorow,either that or he is going to return to stock:blink: Quote Link to comment Share on other sites More sharing options...
