I need help. I have a 1995 Subaru legacy wagon 5 spd.She has been stalling and dying constantly. This is what I have done so far: changed spark plugs and wires. Changed fuel filter. Changed core.Changed throttle position sensor.Cleaned throttle housing.retrieve codes(throttle pos.sensor. misfire in engine 1 and 3) She has all the symptoms of a bad Erg valve. Stalling loss of power bad fuel mileage. But erg is not where it should be. Even had a shop look we are stumped as it say my car has one. What I haven't done:fuel injectors. Oxygen sensor. Erg.) Car is costing me a lot of money. Can anyone help please? Thank you Chylla

Did anyone answer? This is in the wrong forum, so most people with these newer cars will not have seen your question.

1995 manuals do not have EGR, it's not supposed to have it, only automatics have EGR in 1995, few mechanics know that.

 

1. voltage/battery/alternator are good?

2. read the codes and post the exact codes here - the actual numbers.

3. *when you have multiple codes*: clear the codes and see which one comes back first - like if one appears right away, read it again immediately and tell us which one.

 

Cylinder misfires: Check timing belt, timing tensinoer, timing pulleys

Check fuel pressure - or i'd just pull the fuel supply line by the fuel filter and crank it over and see how much it comes out - i've diagnosed cars in 30 seconds like that before. If it doesn't come out as a steady stream like a garden hose, something isn't right.

 

Throttle Position Sensor - replace it with a used one. If it didn't work, replace it again or make sure it's installed properly.

If you still have a TPS code after replacing the TPS - then check the wiring for the TPS sensor - there are two possible ways:

 

A. Start right at the TPS connector and work your way backwards on the wiring harness - wiggle the wires aggressively while the car is running. A change in idling/running while massaging the wires will indicate a wiring issue in the harness. splice in new wire.

 

B. check resistance/continuity between TPS connector and main engine/intake manifold connector - really easy as they're both adjacent to each other, only a foot apart.

Idle air control valve? My old '97 had a bad one and it was pretty hard to start and had a rough idle. A new one cleared it right up. On our Lexus, when the IACV died, the car would not idle at all. Unfortunately, they are pretty pricey.
