  1. When I started this ordeal a while back,  the first question I wondered is how exactly does the computer determine a misfire. From what I have seen and read,  the computer looks at the crank sensor and if it determines that the crank speed is different than what it is looking for, it throws the code.

     

    Some of the things I asked myself were what would cause a cylinder to slow down? My inital answer, poor ignition.  Next questions was what parts are associated with that? Etc and go from there.

     

    I would start with the simple things first. Pull the plugs and check. Pull the crank sensor and check. I have heard about crud building up on the sensor causing them to drop the magnetic field that triggers them. Spray the coil with water. Check your timing.

     

    Since it is happening at idle it seems that it what ever is causing it is pretty severe. 

     

    Then if you do start changing parts, go one at a time. This way you can be certain that you have actually fixed what was wrong.

     

    If I had not had an issue with a Hyundai I once owned, I would of called BS on the plug wire issue. I went through 4 sets of aftermarket wires before I returned them and bought OEM wires.  

     

    Hope that helps.

  2. well the other platinum plugs are only $15 so only 5 more.. if it was a sohc I would not bother with the platinum plugs. Funny thing is if I have a misdirected on 1-3 how is it still pretty smooth giving the firing order... Maybe its my exhaust leak right at the header output?

     

    Mine never gave any symptoms of a misfire either. The code usually occured durning high speed cruising on the highway and the light would start flashing. 

  3. Here is the repair I did along with a write up. http://www.ultimatesubaru.org/forum/topic/109623-shifter-linkage-replacement/

     

    From a wear stand point, I suppose the thing that the most damage would occur where there is metal to metal contact on the knucle where the bushings are worn out. Mine was rattling and being annoying so I changed it.

     

    Good luck.

  4. I have put the tone rings on and made them reasonalby tight with an allen wrench. You know, not Bruce Banner tight but nice and tight.

     

    On a second note, something I have not seen mentioned is that you might want to remove the ABS sensor from the knucke if possible. This way when you hit the stud with the hammer you don't impart severe shock to the sensor.

     

    Has any one done this without removing the sensor and not have any problems? Just curious. :cool:

     

    Good Luck!

  5. This is what you might be looking for. They are like a stripped screw removal tool. They will slip over the wheel lock and as you turn to get it off, they get a tighter grip. There are cheaper sets out there. This is what I happen to find quickly.

  6. How's the rest of the car holding up at its mileage and how are you planning on using the car normally are some of the things I would be looking at.

     

    Although you could always swap all the parts over to a newer car if you stayed in that model family.

     

    I considered swapping my mounts to group n until I read about the increased noise inthe cabin. My car is primarily used for everyday commuting and hauling the family around so that was not really desirable. Plus I don't plan on racing it anytime soon...... :lol:

  7. the pickup changed on the newer cars has a heavy bell type strainer thiss weighs more and whould definatny vibrate more than the original ones.Anyway today i'm taking apart a 2.5 1 from a 2001 forester blown headgaskets runs very good still no slap or knocks 210000kms whant to use it as experiment to see what berrings look like on a engine thats running fine with no bottom end problems will take detailed picks of the berrings and post them here will see how they look if i can get past the 6 engine jobs in the way first

     

     

    I would disagree as the heavier pickup should have a dampening effect on vibration.

     

    Adding/subtracting weight is how you move the resonant frequency of a device out of the problem area.

  8. It can. I had a cheap autozone alt go bad within 200 miles of installing it.

     

    Since you can feel the alt freeze up as you turn it that you found atleast one problem. Sounds like one of the bearings in the alt went bad.

     

    I would also at the very least replace the bubbled hose too and go from there.

     

    Like some of the other responses mentioned, get a mechanics stethoscope. They are great for finding problems like this. Harbor Freight has one (pn 41966) for 3.99.

     

    Good luck!
