    Dear All,
    I just bought this car for few months. It is sv4 year 94 (A) 2.0. The FC is very high RM50 can go around 160KM only (city drive) or 6.14KM/L.
    I went tuning and the Honda Specialist told me to change fuel pump (I changed only the motor caz the whole set cost RM600-700), fuel filter and sparkplugs. I don't feel there is much improvement. FC still very high. I already spend RM450 for the service including labour charge. So, all sifu what else i can do? what went wrong?

    Your advice is much appreciated. Thanks.

    i had a frnd who had FC probs on his SV4 and he went to Honda to get a diagnostic reading on his ECU......I think they had reset all his parameters to factory settings as his were all not......maybe you could try this....regards

    The F20A 2.0cc SV4 engine is a hevy fuel drunker.
    Nothing much u can do.
    Have to live with it, since u already bought it... or else plonk in H22A.

    Masalahnya, H22A also fuel drunker..but of course better than F20A lah.

    Dear All,
    Thanks for your reply. If my FC really consider normal then i have to bear with it already. Do you all know any fuel saving device in the market i can install to improve the FC? or i can consider converting my car into NGV...:hmmmm: but Natural gas price is going up soon...

    oh ya... can i swap my engine to 1.8 one? hehe...(like the civic 1.8 latest model)

    change to manual tranny would save a lot of fuel. Putting 1.8cc (k18 etc) won't save your Fc problem also since SV4 chasis damn berat!.

    ur fuel consumption is very high....i dont think that is normal. iv used both f20 sohc and converted to h22 currently...and for me very slight different which h22 consume more due to it is built for performance...basicaly try a few easy way of troubleshooting if ur consumption is high...

    1. Choked air cleaner - change new
    2. Spark plug - inspect for carbon or engine oil...too much carbon means ur a/f is out.
    3. clean ur injector - buy the injector cleaner or pump in d shell v-power couple of time.
    4. wat about power? any slugish feel...check on the vacuum system, maybe cracked hoses.
    5. tyre pressure.
    6. foot pressure...most important..:proud:
