While running on LPG and braking to a stop, the revs on my V70 Bi Fuel die and engine cuts out. It only happens while slowly coming to a halt. I can only think that it's the extra power requirement needed by the ABS. Does anyone else put up with this?

It is the servo changing the manifold vacuum that bringing the cutting out on.
The cause is poor fuel mixture control, it might be time to give the stepper motor a flush out again. Increasing the gas pressure a little could also help but you might end causing other problems doing that. |

Do you sometimes get a hissing sound from under the dashboard when applying the brakes? That it classic signs of servo fault on P2 V70s.

Thanks. I will give it a flush out. Last time I did it was 10k miles ago but never had cutting out before while braking to a halt. Simon Thanks. No hissing and braking efficiently. Just annoying stalling sometimes coming to a halt. |
