| It sounds like you have a sticky ISV - which you should clean with
| _throttlebody cleaner_(NOT CARBURETOR CLEANER), or check the condition
| of the throttle switch.
Throttle switch is OK it goes on just when it is suppose to, and I
cleaned ISV with carburetor cleaner :-( and 9 V battery. Everything
works OK running on petrol, it's LPG that is troubling me.
Hire is in short how it works: Engine is always started on petrol, and
runs on petrol for few minutes, until engine warms up. Then it switches
to LPG. LPG is in liquid state in tank, goes to evaporator (warmed with
coolant from car cooling system so it does not freeze), and there it
evaporates and goes into intake mainfold trough rubber hose. When engine
idles LPG is going trough ISV. So all the electronic, O2 sensor... have
no effect when engine is running on LPG. Sort of very simple carburetor.
Only thing that can be adjusted is idle (with a knob on evaporator).
Since ISV is constantly working I have trouble adjusting idle so I try
to disconnect it but engine died. So it seems that my idea about running
engine with ISV disconnected is no good :-)
| If the ISV is a 2 contact unit, if you can
| blow through the unit (after it's cleaned, of course) without power,
| then it's no good.
It's 2 contact unit, I'll try that.
| If it's a 3 contact unit, then it is supposed to
| allow air through at rest. When you clean the ISV, use a 9volt
| battery to make the valve click to ensure that it is not siezed.
Did that while I was cleaning ISV, it is working. I also did the test by
inserting fuse in one of relay's in fuse box for few seconds, and than
by activating full throttle switch, and it's clicking.
| If the LPG system acts like a normal fuel system, the shutdown of the
| switch or of the ISV shouldn't harm it, it will just idle poorly.
As I said it does, so much for my idea.
BTW how do you adjust timing on this car, how do you loosen distributor
when there is bolt at it's base?
I hope you can understand what I am writing, my English is far from
perfect, and I still have to learn all mechanic words :-)
