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 ?
