1992 Legacy Turbo - engine cuts out
I have a 1992 Legacy Turbo 5MT. when I first start this car it idles at a high rpm and rough but it will idle down when it gets warm, almost to the point that it stalls.
When I drive the car it bucks and hesitates (neck snapping) and if I push the gas a little harder it backfires thru the throttle body, pushing the accelerator to the floor causes the engine to completely cut out to the point that if I kept my foot to the floor it would stop running. After I remove my battery cable for an hour to prepare to check the codes I get about 7 codes. When I do the D-check I get a code 35 (Canister purge solenoid valve) could this be the cause of all this trouble ? I would appreciated any help with this problem. Thank You. Bill

Is it quad cam? If it is, what are the other Seven codes...?
In my previous experience, purge solenoid will throw code 22:Knock Sensor. also;oxy sensor may trigger a code as well. Basically, I would check the Purge solenoid, firstly, check voltage at pin 1, (pin on left when looking at plug while disconnected), you should have 12v with Ignition on. Then turn the ignition off and check the resistance between terminals 1 and 2, it should be around 36 Ohms. Also, most times I had this many codes, it was the Ign/EFI Relay, (or main Relay). (people are a bit slow to start, most people want info before they give theirs up!LOL!) Hope this helps, Cheers, Sixpack Subaru Sixpack Subaru |

Is the EJ22T a single or dual cam ?
These are the coded I get on a regular basis (22) Knock sensor (24) Air control valve (31) Throttle sensor (32) Oxygen sensor (35) Canister purge solenoid valve (45) Atmospheric pressure sensor. I get the code 35 on a d-check drive. One minute it will run great the next minute I am pulled over to the side of the road with the engine shaking the car at an idle under 500rmp. I will check the voltage at the pin on the plug. Thanks for the response and information. Bill |

The EJ22T in the Legacy was a SOHC.

Oh! There they go!!LOL!
Yeah check out the voltages/resistances at the purge, if they check out OK, I would put a new ignition/EFI relay in. I have only ever seen ALL these codes come up together for this reason if it was NOT the purge solenoid. Sixpack |

you have a bad coolant temperature sensor, it is under the intake manifold on the water bridge. It is very close to the knock sensor.
I bet %95 that this is the problem. I have had it, and many many others have had it as well. |

does this sensor have a 2 pin plug, could you tell me is it closer to the driver or passenger side.

my guess is "(45) Atmospheric pressure sensor."
$400 part, very hard to find, as they don't make them anymore I'm told it's a little black square sensor in front of the passenger side strut tower, with 1 hose going to the underside of it. It uses a gray, 3-wire triangular connector. I hope that this isn't your problem, but mine has gone out twice, and your symptoms sound similar. I found that what happens is that if you boost over 0psi, it cuts fuel. |

I just love the way that when someone has a fault, they instantly assume that EVERY single car that presents with the same symptoms is going to require the same rework/rectification/replacement part/s. If you guys were all mechanics we would go out of business in a flash by selling parts that are not needed. It's nice to jump in to help people who desperatley need it. But how can somebody say with 95% accuracy what the fault is with a vehicle they have never seen/heard or worked on? I am not flaming anybody here and all these points have bben VERY valid and i have taken all these things into account. I just believe that when we are putting our 2 cents worth in, we should advise that it is in our opinion, or in our experience, or I have read....
Again....I'm not trying to piss anyone off....This thread just reads like everyone KNOWS what the problem is because they've already had it and fixed it on their own wheels. CHeers though Everyone...good work. |

Here goes; I have never replaced a coolant temp sensor without it throwing a code to alert me it was faulty.
but;should have 5v reference voltage from ECU at coolant temp sensor, check the resistance of the sensor ranges progressively from 2.0-3.0 Ohms@20degC to 270-370 Ohms@80 Deg C. check knock sensor resistance to ground should be 560K Ohms. This is the ONLY test for knock sensor other than continuity to ECU, as the Knock sensor creates its own 1v AC current through piezoceramic/electric Element/Crystal. Can't remeber anything else at the mo' Cheers |

Sixpack,
No news yet. Snowy, cold and no garage. I did test the Atmospheric pressure sensor and its not that, it was easy to reach and quick to test. I received a canister purge solenoid valve. I want to install that valve so I don't get code 35 during d-check. I'm starting to think I have a bad ground. My radio gets lousy reception and I can hear enging noise, this just started in the last few days I will post any updates. . . Bill |

Well, for the fact the temp sensor is a $5 part at a junkyard, I would replace it.
Mine NEVER EVER EVER EVER threw a code. And then I swapped the damn motor into mine car (from my wifes donor) and it NEVER EVER EVER threw a code. But I would have the same damn problem. Sometimes. Then it became every start up. Then I replaced it for $5. OK, so my %95 might be a tad high, but...... I would lay some money on it, at least against other peoples ideas. |

Hey Reddevil??
Do you still have the old sensor? Check it out as per the same specs above!!!LOL!! (FIVE BUCKS!!! they would charge us about $50 Aus as a new one is something like $78.78, or something.......). You may well be right! not the first time for the first time!!!LOL! Cheers Sixpack |

When I removed it, it came apart, hense the problems it was causing.
All 90-94 subaru legacies are now relegated to the U-Pull-It junkyards now. There are always at least 10-20 legacies to get parts from. Small sensors run from $2.50 (ignitors), temp sensor $5, coil pack $20(?). A complete running engine and tranny, if you get there first, goes for $275. ($150 motor, $125 tranny). I got a 2.2 turbo block, with heads, exhaust, uppipe and turbo for $125. Whenever I am there, I just pick up extra sensors for use later. |

I installed the canister purge solenoid today, the check
engine light is finally off but problems still exist. The ingine will not warm up on it's own, you have to give it throttle. Once it's warm it idles ok but not great. On the road it will cruise but you can't be agressive or it backfires thru the throttle body. Any suggestions ? |
