Have you connected a vac gauge up to test for vac leaks.....

also, trace the ICV wies through the loom to the ECU checking for breaks.

You've got one built into your LPG system :y

It was showing about 0.3 bar absolute fully warmed up when we set it up, IIRC.

The code seems to point to a dodgy ICV circuit, which would certainly explain the symptoms.

A typical good engine vaccum should be 20 Ins Hg......which is about -700mB...........

And a vaccum gauge should be available from any good car shop.....i.e. the Gunsons Lo-Gauge.

Its also possibly one of my most used diag tools as it gives a good quick relaible indication of the engine condition.....and helps to diag faults in the vac accuated components to.

That ties in with what the LPG system was reading when it was working OK. 300mb absolute = 700mb of vacuum. So, has it changed (when hot - it won't be asm much when cold)?

Its likely to be slightly more (or vice versa if working off absolute) when warm than when cold as engine vaccum should be better.
