G'day thrillseekers. I am having problems with the LPG system in a EF GLi. It is a Tickford system.
The motor surges on idle in neutral, down to an almost stall, and back up again and it almost stalls when coming to a stop in gear. (auto) I use left foot braking a lot!! I have checked the balance pipe for leaks, I have checked the idle valve for blockages, I have cleaned the ICS (twice), all to no avail. I am thinking there may be a vacuum leak somewhere in the aircon valve operating system. Would this be possible? Although I can't hear anything suspicious. I haven't yet put a vacuum guage on the engine. If anybody has any ideas, I would be most gratefull |

Or the idle circuit may be blocked.You will know this as it will stall when coming to a stop (going around a round about ) and won't idle.

i have a problem of the car backfiring and when it does it blows this little noby thing off causing the vacuum leak and the car to idle like a pig. If your car has backfired before then this might be the problem. The little noby thing is next to the injectors to the right u should see a valve with protected or open... that may be ur problem.
If you need a pic let me know |

I've checked the idle curcuit, eaglus, by removing the solenoid and poking a thin wire thro' the idle jet, and also checked the solenoid works. And I know the piece you are talking about, efweapon, and that is in place. I have experienced that before, one can uaualy tell by the intake noise that the cover is missing!

Oke' You have not mentioned how it is on petrol??? When the last time you have done the self learn???

It doesn't run too well on petrol, but I think it may be because it rarely is put on petrol, and the injectors may be stuffed. I don't think it has really run on perol for at least 2 years.!!
I'm not confident about doing the self learn in case I stuff up the LPG computer. I have read the article about it in the forum. |

I had a similar problem with my AuII XLS. Ended up being the spark plug leads arching out. Replaced them and it was all good. A friend had the same problem and new leads fixed it for him too. Hope this helps.
@ efweapon - My car was backfiring too from the faulty leads. Was blowing the vacuum hose off regularly. Could be worth having a look at the leads on yours too. |
