    Not Hitachi? What kind? I don`t know how they go out of adjustment with out fiddling,but,they do.
  2. naru
    Sounds like. Try unplugging it or blocking the inlet tube after the motor warms up.See what happens.

    Sight glass = first thing to check Had one last week that was too low.Adjustment gave tremendously improved drivability. If the fuel level is too high,idle mixture will be richer. It is difficult to reconcile your rich idle with a vacuum leak unless the float level is too high or the idle air bleed passages are restricted. You might try disconecting the charcoal cannister(if so equipped) in case it is somehow adding gasoline vapour at idle. Gasket Goo around carbs never works,in my experience. Make yourself some thicker gaskets.

    Testing purposes?? That is what a gauge is for. Used pumps are in the same catergory as used toilet paper as far as I am concerned. Measure volume w/a quart jar. You are making this more difficult than it needs to be.

    Still sounds like a vacuum or unmetered air leak to me. As the Auxilary Air Valve warms up it decreases the idle air supply. Unmetered air now makes up a greater percentage of the total air thus leaning the mixture to the point of uncombustibility.

    +1 I had 36 psi,but,no volume.Ran better than expected.

    Recheck your fuel pressure.That will tell you everything you need to know about the reg. and more.The numbers seem questionable. I was taught that a fuel pressure check is the FIRST thing to do on a poorly running injected engine. I`ve found it to be good advice.Saves a lot of time and effort.
  9. naru
    The fuel pressures you quote are incorrect. Fuel pressure should be 36 psi above intake manifold pressure. So 36 psi w/engine stopped. 25 psi w/engine idling assuming 19 inches Hg(-9 psi) of intake vacuum. Approaching 36 psi at WOT.

    It is not the coil nor thermostat. Since it is OK w/choke on,it is too lean for some reason.Probably a vacuum leak. It would be worth giving the PCV a shake to make sure it is not frozen or just replace it. I`d suspect the intake gasket on the 2/4 side first.Plenty of other possibilities though. Forget random part-buying rampages.They are dumb and costly.
  11. naru
    Probable-No.Possible-probably. Should be easy enough to check w/a timing light. Compression is kinda low. SPFI wants something in the 130-155 psi range. Might be enough to explain the performance differences. Probably explains why additional advance helped matters. I would advance 2 more degrees and then 2 more etc.as long as it improves. How does it perform during a short full throttle run on the flat? Does it hold fuel pressure all the way up the hill? TPS ohm out OK? Got another MAF to try?
  12. naru
    You don`t even need a pinout, Leave it plugged in and use your voltmeter to find the one whose voltage varies.w/moving the flap. Main thing to note is the smoothness of the variation.There should be no sudden wonky spots. Never say never,but,a MAF failure seems unlikely.
  13. naru
    No need to waste time and money guessing. Shut it off quickly after a "buck" event and check the fuel level in the sight glass.
  14. naru
    That does not mean the MAF is faulty. When you unplug it,computer richens mixture as a safety feature possibly counteracting a vacuum/unmetered air leak. I would monitor the MAF output voltage while moving the flap by hand. Any defects should be obvious, Cleaning flapper style MAFs is not a common procedure. Sometimes,the track wears,There is a fix, Any problem will be easily spotted w/a voltmeter.

    Housing looks very similar to a Hitachi AFH 50-06 as used on 1.6-2.0 litre Nissans. Note the cast boss below the electronics in photo #2. http://www.ebay.com/itm/91-92-93-94-95-NISSAN-SENTRA-INFINITI-AIR-FLOW-SENSOR-22680-53J00-AFH50-06-/181067642869?pt=Motors_Car_Truck_Parts_Accessories&hash=item2a2878f7f5&vxp=mtr#ht_743wt_896

    I`d take traction control over a LSD any day. I first experienced traction control in a cheapo mid-early 90s Ford fwd van. I was thouroghly impressed. Have since experienced a full size ford van go through low traction situations that would have stopped it w/o traction control. Just agreeing w/the OP.Traction control equipped cars ARE superior. Wish I had it on my 84.
  17. naru
    Not the traction control equipped ones. Traction control is a great addition to any 2 or 4wd vechicle for winter driving.It greatly increases capability. I`ve had ones that would not move in the snow until the traction control was turned on.

    I think someone swapped the wrong hotwire into the wrong housing during a "rebuild". Note the fresh looking QA sticker and the different looking screws w/no dirt in the recesses.Shiny housing too. ER27s and mpfi ea82s use 22680-AA110 instead of 22680-AA100 so it is easy to see how a mistake might be made.

    Since it only happens after shutdown,it is probably a fouled spark plug. Pull and inspect them after 20 minutes.Coolant or fuel Find the dead cylinder by removing plug wires one at a time.

    Check that the carb accelerator pump squirts.

    ECU is not invovled. Search FPCU http://www.ultimatesubaru.org/forum/topic/113548-fuel-pump-relay-location/?hl=fpcu&do=findComment&comment=954494

    Start by checking the fuel level in the carb sight glass(I love those). Free and fairly easy. Sounds like it might be too low because of a pump/filter problem. Change both fuel filters regardless. Check that the carb accelerator pump squirts. Looking at the plugs is free and easy too. Ditto for checking the plug wires.
  23. naru
    Belts break.Oh yeah. I would not worry about the brand though,

    You have it backwards my friend. O2 sensor will see extra O2(that never went through the engine) from the leak causing the computer to THINK the motor is lean and add extra fuel resulting in an intake mixture that is too RICH.
