Re: Manual gearbox Stall.

Its just part of the evulation of finding the soluation. I need to run some tests tonight but it appears the adjuster on the throttle butterfly is not reliable enough to stay on the adjustment set. If this proves correct I need to make the change on the Idle valve.

This methord would be more work but would be better overall.

Re: Manual gearbox Stall.

Apart from one day when the stall returned and I made a adjustment to the throttle body butterflys the car has been running well and not stalling. What I want to do is make the change I mentioned below, over all the current changes are and improvement.

Re: Manual gearbox Stall.

About a week ago is the last time the car stalled, I adjusted the throttle body and the problem has gone away. It may be a matter of getting the right balance between the base line air throught the throttle body.

I will keep you posted as I learn more.

Re: Manual gearbox Stall.

Okay I have been driving the car around with this mod for the last couple of months and I can say that the stall issue is gone. Given that I have a twin plate metal clutch you would expect this to still be a problem but it is not.

The way I did it was a bit of a cheats way and not the best method but it worked.

Re: Manual gearbox Stall.

Okay bit of a update as you are aware I adjusted my idle manually. Anyway or reason that are a long story not worth telling I decided to experiment with the Subaru Select Monitor and compare the reading on the ECU.
Comparsion was between
stock standard 92 Auto SVX
My Manual 1995 6 speed set up car (the one I manual adjust the idle on)

When I compare the two out puts surprise surprise I find that the Auto shows the "IDLE VALVE" ON when the car is idling.
The 6 speed shows it OFF and there is nothing I can do to get it to go on

In the manual in the section on Fuel Injector System, there is a table "Output Modes of Select Monitor" Down the table it shows FA0 over the next page it list all the outputs under this section it shows idle switch ID. So that is the sucker that is not turning on and letting the car idle.


So team what happens to turn this on, any ideas.

Tony

Re: Manual gearbox Stall.

Could it be something the tcu turned on and off when it was in park or neutral and therefore no load on the engine?

Re: Manual gearbox Stall.

If I understand correctly you prevent the butterflies from closing? If yes, then could it be that the ECU thinks that your are not idling (against the BF stops), but pressing the pedal and it closes the idle air bypass?

Re: Manual gearbox Stall.

Figured this much out,
TPS output voltage has to be below .4V or the idle valve is'ent turned on. My TPS was reading .6V.
At this point it did stop the stall (I had adjusted out my opening of butterflys).

I need to figure what happens when the idle control valves opens and see if the so call valve is opening.

Anyone know with certianity which valve it is.

Tony

Re: Manual gearbox Stall.

Tapani what you say is sort of correct with the stop working I had the TPS reading .85V with them adjusted out, it read .6v still no valve opening. so I adjusted the TPS itself.

Still need to see if the gear change sensors have and effect.

Re: Manual gearbox Stall.

The ECU also looks at the engine rpm - not only the TPS.

If you want to leave the butterflies a crack open - you may try setting them so that the engine idles below the normal speed... this way it acts as a "backup" only and lets the ECU adjust the speed? What do you think?

Re: Manual gearbox Stall.

Tapani that seems to be correct and possiable temp.
What we know,
TPS voltage has to be below .4V,
Idle around 1,000 not sure if this change based on heat,

But it still won't idles normally without me cranking the butterfly open slightly.
Got me stuffed.

Re: Manual gearbox Stall.

Okay can't seem to get the "Idle Switch" to turn on again but I have got the car to idle better. As part of checking I found that the left O2 sensor wasn't working, at this time the car had no hope of idling. Found the main harness wires broken so repaired that a install a different O2 sensor. Still didn't idle checked the monitor and the left back was over injecting by 38%, bad sensor.

Replaced the sensor and now it idles a bit rough but it does idle which is a surprise, its dark now so I will have a look tomorrow and see what more I find.

Re: Manual gearbox Stall.

You do know that the O2 sensor wires (from the sensor upto the connector) may not be repaired by soldering, yes? The sensor gets the ambient O2 reference thru the wires - inside the insulation. Weird, but true.

You said "main harness" so probably you were fixing another part of it - not the sensor wires themselves.
