uniberp Posted December 20, 2006 Share Posted December 20, 2006 Is it normal for the idle at cold to smell really rich? 97 leg 2.2 autoawd I mean really, I caught whiff of it in the back hall this morning before leaving the house. Could be the catalytic convertor failing at 140k miles, but no CEL yet. I get good mileage, 30hiway 25city, so I assume it's running well, no strange noises or shakes. Anybody make any changes to affect that? Quote Link to comment Share on other sites More sharing options...
Richard1296 Posted December 20, 2006 Share Posted December 20, 2006 Does your CEL work , one that had a dead bulb hid my problem from me...never noticed it didn't light in test mode. My 2000 had a real rich cold idle but did fine when warmed up. Mine was the Oxygen Sensor, but again the bulb was out and was my reason for no CEL .

porcupine73 Posted December 21, 2006 Share Posted December 21, 2006 My '96 I can smell a little raw gasoline in the exhaust on startup. I'd guess if any of the sensors such as MAF/MAP/ECT is real inacurate maybe it might make it run extra rich? Or if there's a vacuum leak maybe making some cylinders run rich. I love the smell of gasoline in the morning....it smells like...victory. Quote Link to comment Share on other sites More sharing options...

Suzam Posted December 25, 2006 Share Posted December 25, 2006 Our 95, 98 and 2001 ALL stink on cold mornings. I usually catch a wiff while backing out of the driveway. You can try switching brands of gas but oxygenated winter mix and the blended gasoline are just a bit stinky until your cats warm up to temp. and the engine gets to operating teperature Quote Link to comment Share on other sites More sharing options...
OB99W Posted January 11, 2007 Share Posted January 11, 2007 i'm bumping this because i have this complaint with my obw and my sisters impreza I realize that this thread is a couple of weeks old, but I thought there might be some interest in Subaru's "official" position on cold start exhaust smell: http://endwrench.com/images/pdfs/ExhaustInfo.pdf Quote Link to comment Share on other sites More sharing options...
