I have a serious problem. I totally closed my intake valve and still have a high rpm of 1,400. I think too much fuel is being used up. I mean the car really drinks gas. I want to know if there is a way to lower the fuel to get the right mixture of air an gas.

 

Is it idleing at 1400 when then engine is warmed up or cold? Does ur car bog when u try to push the gas pedal. Are u getting any check engine lights? Take ur spark plugs out and see if u're truly running rich.

 

its at 1400rpm when warmed up higher when cold. Yes it boggs sometimes. but i'll check the plugs 2morrow. but is there a valve somewhere for the fuel? Its a 91 DA RS
