Check your TPS or your O2 sensor..

there's no check engine light on and i canot do the cel diagnosis cuz i cannot find the diagnosis plug.

throttle cable jammed up?

no,i've checked all this.i think is the ignition for the spark plugs.i will check that also very soon..for now i have to change a planetary

i'v removed and cleaned the carb and nu effect.also checked the throtle cable,all vacuum hozes and the tps senzor but no change.

it was an error at the vacuum and i fixed it today.i made a consumtion test L5,7l/102km.perfect..yeeeeeyyy

Hi i have same problem my car runs 10L on 100 Km and i drive normal fastest is 80 kmh with change gears on 2500 rpm... How to fix that ?

When you say it was a vacuum error what do you mean? I have the same engine, I get good fuel consumption but I do have a really bad idle problem that's affected by the electrics being turned on

do u have some black box? with around 15 black chitterlings? last 2 are for fuel dont touch them. Others are for air and vacuum... Maybe u cant see but some of them are maybe broken. Try to change all of them expect fuel ones that are on the bottom. And change Step engine is located http://honda-club.cz/forum/files/tt_185.jpg this is google picture so dont focus on the red thing ... Step engine is the thing on intake header that has jack pluged in.

I will check at first all vacuum hoses.
