VT II S V6 Lacking power on LPG

[MattyC]

Hey guys, i have a dual fuel ecotec v6 and when i'm on gas it turns to shit when the car gets warm, and yesterday i went to the beach and after a few hours at the beach. hopped in the car and tried to reverse out of the parking, the car was at 500rpm!! with my foot 3/4 down. :/
Then after sitting there revving the engine for like 30 seconds, it got a bit of power back and then as i turned out of the parking lot got pulled over by the police! 10 meters of driving and BAM! hahaha but besides that it got some power back but still not alot.

Is there some kind of GAS pump or something that may be a bit dodge that limits the gas or whatever?

Cheers.

that sounds weird, take the car to the gas converter you got it from, sounds like something is wrong with your setup.

also try throttle body & carby cleaner. maybe injectors have ran dry too much, so check them too.

yes, very strange symptom.

i run my car on petrol at least once a week to get its power back again.
car was converted by previous owner, i'll look into it.

cheers

How much gas is left in the tank? That sounds like what happens when the tank runs dry. If there is gas in the tank, possibly the convertor is at fault.

Yeah i'm thinking it's a faulty converter, had a 3/4 tank at that time. I'll get it seen to sometime.

Maybe need a gas tune, alot cheaper than relacing the convertor

[MattyC]

quick question, do I have to go to a special LPG servicing place? or do mechanic's do gas tunes?

cheers

Tuning, anyone is entitled to do. Anything requiring disassembly of the LPG components requires a licenced person. My guess would be that something will need dissassembly.

Most parts can be overhauled rather than replaced, including the filters in the fuel lock offs. (The current high A$ should help with the cost of parts.)

Air leaks and cracked hoses, that's something you can replace cheaply yourself, will cause what you have described... and is most likely the problem.

ive also been having to fill up with gas twice a week now :S
ill check up on if i can replace the hoses etc. i'll have a look at it tomorrow
