  1. P0420 - Catalytic Converter Efficiency Below Threshold

    Problems, Maintenance, and Warranty
    Work around In the "Any ideas?" catagory: This worked for my 2000 Forester (California Emissions) with 248,385 miles on it. If you thinks you've spend enough money, try this. Just read the entire first post, the rest is just chit-chat..O2 Foolers, The Economical, Electrical Way!! The parts...
  2. P0420 - Catalytic Converter Efficiency Below Threshold

    Problems, Maintenance, and Warranty
    Please read the entire first post in the Audi link O2 Foolers, The Economical, Electrical Way!!. Many diodes don't turn on until .3 volts. The ECU could read below .3 volts as an open circuit and set the P0136 code. The ECU is looking for .2 to .8 volts, the diode-resister circuit locks it in at...
  3. P0420 - Catalytic Converter Efficiency Below Threshold

    Problems, Maintenance, and Warranty
    Poor crimp is the most logical. OR: You could try what Audi people do. All these parts are on an ATX style computer power supply board. O2 Foolers, The Economical, Electrical Way!!
  4. P0420 - Catalytic Converter Efficiency Below Threshold

    Problems, Maintenance, and Warranty
    Hi Amber, P2270 is actually a P0136 code, too much air in exhaust or faulty harness/wiring. See this post. http://www.subaruforester.org/vbulletin/f88/02-subaru-forester-p0136-see-p2270-p2271-intermittent-idling-fluctuation-hesitati-107001/

  6. ('98-'00) P 0440 cel

    Problems, Maintenance, and Warranty
    On my 2000, my son's 2001 and my daughter-in-laws 2001 it was the fuel filler neck and the valve that is at the top of the neck (see pictures in this link). http://www.subaruforester.org/vbulletin/f88/5-mechanical-fix-p0440-59207/#post656563
  7. Lifter ticking 1998 forester

    EJ25 - 2.5L Non-Turbo (1998-2010)
    Valve adjustment? I hear many Foresters drive by with ticking from the valve adjustment (or lack of adjustment). Valves (without hydraulic lifters) are supposed to be adjusted at the same interval as timing belt replacement, 105k miles. Click on the SOA link on this link...
  8. ('98-'00) Hard shifting when cold

    Problems, Maintenance, and Warranty
    Trans-X Trans-X has helped my 2000 Forester and my son's 2001 Forester. Add to your transmission, don't overfill.
  9. Keyless entry will not work!

    Interior and Electronics
    Welcome to the forum. A cable may have come unplugged from the Keyless module. Do you know if it's a factory Keyless or an after market? Mine has an aftermarket Clifford and was beautifully installed.
  10. ’02 Subaru Forester P0136 (see P2270, P2271) intermittent idling fluctuation/hesitati

    Problems, Maintenance, and Warranty
    Welcome to the forum. I knew this thread would get moved to the one with the OBD2 Code "Sticky". P0136 is a circuit malfunction, leaning toward a harness open or short - or a bad connection at the terminal ends (at the ECU or O2 Sensor) of the harness. The terminal ends can push out of the...
  11. ('03-'05) Problems going over 90 MPH

    Problems, Maintenance, and Warranty
    I think you're on the right track with the mounts (engine, trans and diff). When you "get on the gas", the mounts should be at their physical limits (safety hooks or fully compressed/expanded) and at partial throttle they should be "floating" - this is usually where they "feel different". When...
  12. P0420 - Catalytic Converter Efficiency Below Threshold

    Problems, Maintenance, and Warranty
    Did you read the 396 posts in the "P0420 Sticky" at the beginning of this forum?
  13. ('98-'00) Unidentified constant noise from the front.

    Problems, Maintenance, and Warranty
    The "bearing inside the clutch assembly", "throw out bearing" and "release bearing" are all the same bearing. To access it, you either pull the transmission or the engine. Clutches are usually sold/replaced as a "kit". The bearing is in the lower left corner. New Original Clutch Kit Impreza...
  14. ('98-'00) European subaru s-turbo 1999 OBD tool

    It's called FreeSSM. FreeSSM - Complete access to your ECM and TCU - Subaru Outback - Subaru Outback Forums This cable works with my 2000 L. http://www.amazon.com/OBD2-Diagnostic-Cable-KKL409-1-VAG-COM/dp/B002WIN8VQ You need a VAG-COM 409 compatible cable.
  15. (All Years) brake groan

    Brakes
    You can try a different brand (formula) of pad or a different grade of the same pad. You can bevel (or change the angle of) the leading edge of the pad. If there is no groove cut in the pad, you can add one (across or diagonal). All the above will change the frequency of the noise and might...

    :icon_biggrin: Perfect answer!
  17. Servicing a IAC valve

    Problems, Maintenance, and Warranty
    Cleaning is the servicing. Many recommend using a piece of wood to clean the pintle and seat so it doesn't get scratched. The spring is delicate, a soft toothbrush works well for the spring and shaft. Try not to let the cleaning solvent track up the shaft into the windings (stepper motor part)...
  18. ('98-'00) Unidentified constant noise from the front.

    Problems, Maintenance, and Warranty
    I've had them be like that for years (no increase in noise) and I've seen them go bad quickly (noise level increases daily or weekly). If the noise level isn't changing, you will probably be ok and can do repairs as time and budget permit. If you're mechanically inclined, you can pull back the...
  19. ('03-'05) viscosity of different synthetic oils

    Problems, Maintenance, and Warranty
    Oil viscosity is only guarantied at certain temperatures. It used to be 0*C and 100*C (32 & 210 F) for mutli-weight oils. Today's oils are still measured at 100*C but the "W" weight now has two variables with temperature, cranking temp and flow temp. There can be as much as a 60% difference in...
  20. ('98-'00) Unidentified constant noise from the front.

    Problems, Maintenance, and Warranty
    With slight pressure, it could be the release bearing (#5 in this link). http://opposedforces.com/parts/forester/en_s10/type_1/manual_transmission/clutch/illustration_1/ With the clutch pedal fully depressed, it could be the input shaft bearing (#21 in this link)...
