well if its deffo overfueling theres only 4 things that can affect it really.
CTS, but you have changed that, but was it the correct one?
MAP sensor, the sensor may be dodgy or theres more chance of the pipework being dodgy, air leak here means it thinks the manifold is has little vacuum and thus runnign at high throttle.
TPS, will not auto matically over ride a dodgy signal from the map sensor.
Lambda, only way for this to go rich is if theres a leak before the sensor in the exhaust. |

washer tubing is not the same and will collapse.
spray carb cleaner through it, it should come out the manifold end, pull ther short bit off the manifold first to make sure. |
