idosubaru Posted February 9, 2007 Share Posted February 9, 2007 left my house and the speedometer didn't work but everything else was fine so i kept driving. the tachometer worked fine. then it stalled a couple times, usually while decelerating it seemed, but could have been a coincidence. one time it stalled, just prior to stalling the RPM's were bouncing all over the place...though the engine obviously wasn't doing that. the check engine light came on briefly then went out before i could check it real-time. since i've owned it, it's had a very random stutter. driving along at low speed, highway speed, or accelerating, anytime really. it would have a very quick 1 second stutter and keep trucking along, no check engine lights. codes from read memory mode were: 32, 33, 35, 42, 51 32 Oxygen sensor or circuit 33 Vehicle speed sensor (VSS) or circuit 35 Canister purge solenoid or circuit 42 Idle switch or circuit 51 Neutral switch (manual transmission)/inhibitor switch (automatic transmission) i'll address all of these, but since i'm supposed to drive a few hundred miles tomorrow, which of these could/would cause the stalling issues? O2 and vehicle speed sensor are not likely to be the culprit. canister purge solenoid or circuit, that doesn't sound like it would either. so 42 and 51 most likely? TPS is sounding suspicious?

GeneralDisorder Posted February 9, 2007 Share Posted February 9, 2007 Idle switch is the only one that would cause a stall condition. *maybe* a really, really bad O2, but not likely. Neutral switch wouldn't do anything at all that you would be able to notice. Sounds like the TPS is either bad, or wants adjustment.

hooziewhatsit Posted February 10, 2007 Share Posted February 10, 2007 You said the tach started jumping all around... the only time I've had that happen was when the distributor was going out/already dead I hope that is isn't it, but you might want to throw a spare one in your car before your trip tomorrow. It sounds like the car started back up after it stalled? -Dave Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted February 10, 2007 Share Posted February 10, 2007 You said the tach started jumping all around... the only time I've had that happen was when the distributor was going out/already dead That's indicative of carb distributors, not FI.

GeneralDisorder Posted February 10, 2007 Share Posted February 10, 2007 It would throw a CAS sensor code if the sensor was dirty, or the interrupter disc was mis-aligned. But generally the FI distributors don't have this problem as they have real bearings for the shaft instead of sleeve bushings. GD Quote Link to comment Share on other sites More sharing options...
idosubaru Posted February 10, 2007 Author Share Posted February 10, 2007 okay, i'll try swapping out a TPS. thanks kids! Quote Link to comment Share on other sites More sharing options...
jeffast Posted February 10, 2007 Share Posted February 10, 2007 fix the speedometer, my xt-6 would stall while coasting when it had no speedo thats why it's throwing a vss code Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted February 10, 2007 Share Posted February 10, 2007 Speed sensor should not cause stalling. Don't even need it hooked up to run. GD Quote Link to comment Share on other sites More sharing options...
idosubaru Posted February 10, 2007 Author Share Posted February 10, 2007 from xt6.net discussion, it looks like purge control solenoid and TPS should be addressed. i've never had any issues with VSS codes either and i've had them in a handful of my XT6's.

idosubaru Posted February 12, 2007 Author Share Posted February 12, 2007 doesn't seem like the TPS and IAC are to blame. car still stalls occassionally. i wouldn't expect it, but i'm going to replace the speedo cable since it's broke and the speedometer doesn't work and see if that helps.

azsubaru Posted February 12, 2007 Share Posted February 12, 2007 just prior to stalling the RPM's were bouncing all over the place... The guys who already responded know a lot more than me, but I had a misadjusted idle switch that was not quite closing and it caused this same thing.

idosubaru Posted February 13, 2007 Author Share Posted February 13, 2007 i replaced the speedo cable yesterday...it was actually twisted and seized instead of snapped. anyway, car hasn't stalled since. so either i haven't driven it enough yet or the speedo cable solved the stalling issue. time will tell. my last auto AWD XT6 i put 20,000+ miles without the speedo hooked up and never had any issues, so i can't imagine this would solve it?
