    Default Buying an 04 GSI Auto (LPG)

    Hi all have a few questions about the 2004 Vectra GSI (LPG) i am thinking of buying.

    The car was awsome when running on petrol and great to drive, however switching to LPG the car spluttered had little power and couldnt get past 50mph and the engine light began to flash. This all sorted itself when i restarted the car on reverted back to petrol. Is this something common that is easily fixed?

    I'm just cautious that the LPG install could have damaged the car an the dealer is trying to get rid! Although it is certified by an approved installer.

    I used to have 2.5 v6 auto, and that had a sport button on it. This one had no sport button and changed gear at 6000rpm when giving it some stick. Is this normal or should it rev higher, was i missing something?

    Any feedback much appreciated, including anything else i should look out for.

    Thanks

    Chris

    If it runs fine on petrol then the LPG kit is either going south or not fitted properly, the GSi was never an LPG option so it's likely to be a Prinz kit fitted by an owner, if the mileage is 80k plus I suspect the LPG kit is knackered, lower and it's probably not been set up right, does it have an LPG certificate with it to say it's roadworthy? it should have one of these btw.

    Gearbox, I wouldn't try thrashing an auto to often, they are best cared for in a caring manner, constant thrashing will result in a light on the dash and a 2k rebuild. hth.

    LPG is certified and mileage is 39k. Spoke to the dealer before and they are fixing it, so hopefully this shouldnt be a problem..

    As mentioned though the engine revved to 6000rpm, i thought it would of been higher as the rev counter goes upto 8000, could the LPG effected performance when running on petrol and gas or am i missing a hidden sport button?

    Car is 2004, FSH and every extra u can get inc leather, sat nav elec sunroof, climate etc, they want 5995, is this a fair deal? Anything else i should be checking out with this model??

    Cheers

    Chris

    it's a bargain....

    just don't expect it to perform as well on LPG as it will on petrol... LPG is harder on the plugs as well, so keep them well changed..

    as for the auto box... of course it changes up at 6,000... just because the rev counter goes to 8,000 doesn't mean it's there to be used..

    the rev limiter is set for a reason.. 8,000 is well into the red zone and why buy a newer car to try and kill it by redlining it everywhere..

    on petrol it'll do mid 20's happily and will survive a long life if you let it change around 5,500 tops... that auto box is strong and the ratios mean the sports button is defunct. if you want to hold the revs ( can't see why as it runs out of steam around 6,000 anyway and yes i do know as i have had the rev limiter removed) then just shift tiptronically......

    buy.. and enjoy....sensibly..

    I must be getting old I have a 3.2 Elite with a manual gearbox and I occasionally change up around the 4K mark which is plenty exciting enough for me.
    Mostly though, I just pootle about changing gear at 3K or lower



    However...



    I have a bike powered Westfield which I use on track, regularly changing up off the limiter at 11.5K, so I guess thats how I get my kicks.

    Its safer to be a loon on a track, on the road, its just madness IMO
