j255c Posted July 17, 2008 Share Posted July 17, 2008 Are/is there any vac line(s) besides the obvious t on the back side of the manifold, map sensor and all the ones located near the alternator? My car is acting extremely erratic regarding a/f recently! Ive looked over the vacation pictures religiously and cannot locate any extra ones, anyone have any tips? 06 TB EVO IX SE stock turbo monster subaru hater Link to comment Share on other sites More sharing options...
qikslvr Posted July 17, 2008 Share Posted July 17, 2008 Is it the stock front o2 sensor or a WBO2 that's off? My LC-1 WBO2 is acting up right now too. It reads real rich at times and jumps from actual AFR to 20.33 to zero to 9.## to whatever. Sometimes it even starts to dip as boost builds and then goes back up to 13.## under WOT and high RPMs. You might want to check the clamps on your intake, turbo inlet, IC hoses and your exhaust seals/gaskets. I've read that pre and post turbo exhaust leaks can suck additional air into the exhuast tract and skew the AFR. I'd think it would blow air out of a leaky gasket, but who knows:confused:. Let's kick this pig! Link to comment Share on other sites More sharing options...
j255c Posted July 17, 2008 Author Share Posted July 17, 2008 wideband is dead on along w/ 02 sensor. The car has stalled quite a few times today, so something is telling me its a mechanical issue in the fueling department. Heres what im thinking: Failing FPR Failing FP Relay Failing Fuel Pump Failing Injector? Clogged Fuel Filter? If anyone on here has had one of these fail plz let me know what your symptoms were... sigh it never ends 06 TB EVO IX SE stock turbo monster subaru hater Link to comment Share on other sites More sharing options...
