Hey guys, My housemate just bought a dual fuel VS 3.8L, and the gas system just got tuned. Apparently, the mixer is a bit noisy (this is what he has told me, I've yet to check it out). I know SFA about gas, but plenty about cars, so does anyone have any ideas as to what it might be (if it does turn out to be the mixer)? Any positive feedback from you BBQ lovers will be much appreciated. Cheers, Tim Some original photos have not been recovered yet.

yeah thats common on GAS ecotecs, My mates do it too! Some are even louder than others, nothing to worry about!

my mums uncle just got his VS Ecotec on Gas too. His mixer is noisy intermittently and when its noisy its annoying

Update: now it occasionally stalls on gas. When this happens, it also won't start on petrol, so it is probably something else. Some original photos have not been recovered yet.

not to sure mate, i have a ecotec on gas, n other than it takes bout 5 seconds of kicking over to start when starting on gas, i dont hear any noises or anything from the mixer... id probs just take it to where ever u get ur gass tuned n ask them... (my car goes to stall now n then on gas, so do most ppls i know that have gas, so i wouldnt worrie to much)

Hey, have any of you guys had the engine light come on when on gas in an Ecotec? Mine does this on gas, then it goes away if I switch to petrol. What does it mean?

Probably a wiring fault in your gas setup. We replaced the CAS on the VS, fixed all the starting issues with the petrol side, but still stalls and won't start on gas. Guess that narrows it down to gas mixer or gas ECU?
