Thomas,

Thanks for the input.

I am suspect this might be the case, the Astra was loosing so much power that water along can not be held responible expecially the water jet has been reduce to 0.4mm from 0.5mm. A 40cc/min flow reduction.

Mike is experience the same power drop effect.

Even the air temperature is quite low in England (8 to 9C), the methanol is still evaporating and if it hiots the temperature sensorm it will supercool the sensor and make the car runs too rich.

I will wait for Mike's comment , if he is willing to relocate the sensor before the water spray so it won't get sprayed.
