    hi, my '94 civic VTi with the D16Y1 engine is running way to rich. It is spitting out carbon and what looks like either water or petrol. I checked the leads the spark is weak so i changed the dizzy cap, sparkplug leads and the rotor but it is still miss firing and the car is chocking. Smoke is coming out exhaust and every time i give it a little rev to about 2500 RPM or over and back off, it will stall. I checked the timing and the timing is perfect. Does any one know what the problem is or what i should do ?

    - If you washed your engine lately you might have gotten water in between your spark plugs and spark plug wires which make it misfire.

    - Check to make sure your spark plugs aren't worn out, and your air filter isn't pluged up

    - one of the sensors on the engine like the tps( throttle position sensor) is messed up

    - You have a vaccum leak some were on the throttle body and or intake manifold making the engine to pump more fuel to keep up with the extra air

    thats all I would know, hope it works out

    oxy sensor is due for a change im not sure about TPS but the car cuts out at idle it wants to stall so i think idle controller is also due for a change ?

    Well what i think is the engine may not be getting enough fuel
    ( change the fuel filter if you haven't)

    If that doesnt fix it get a Haynes repair manual and a volt meter and check the TPS( on the side of the throttle body, and the MAP( on top of throttle body) and anything else it could be
