LPG Woes?

well, since posting my last post about my transmission having issues i've taken the car to an auto trans specialist only for him to tell me its not the trans.
now i'm noticing that its doing it on LPG, and it seems to be ok on petrol (running rough at times though). So i'm wondering what could be causing my car to hit such low revs when slowing from ~80km/h.
it is ok if cruising at low speeds (under 60) but anything over and it seems to be almost stalling when coming to a stop.

Re: LPG Woes?

You've already got a thread going on this, getting your moneys worth? :)

Have you checked for fault codes yet, that's the first place to start - there's over 100 of them, so chances are it will be one of them.

Re: LPG Woes?

nah, i got a thread on thinking it was the auto, i've pretty much ruled that out now.
i'm getting the fault codes tomorrow so hopefully it should shed some light on things.

Re: LPG Woes?

if the air piping that goes to the throttle body is slightly cracked (prolly from a back fire) then would that cause my problem?
and what is the best way to avoid this happening again? EL Piping?

If the crack is after the LPG inlet then it would probably be it. LPG usually relies completely on engine vaccuum, if air can get in it will lean the mixture right out. When your braking the vaccuum at its lowest. Makes sense...

Just like a Tsunami.

Re: LPG Woes?



the blue lines are where its cracked.
i dunno if it'd cause problems though coz it still seals ok.
can't think of anything that could be causing it :/

Does it hiss?
If not the cracks are not leaking...
I'd still look at the tranny or computer myself.
