Thought it was a bit fast! Any idea if you can turn it down?

Its controlled by the ECU so I'd check the throttle pedal connectors are clean and secure and I'd also make sure the air filter is clean. Unplug the MAF (air flow meter) and see if that makes a difference. I'd also check and clean the MAP (inlet manifold pressure) sensor.

all the above + the AAP sensor(the one in the side of the airbox)... by the way, is your temp. gauge working well?..cos if the coolant temp sensor gives bad signal the ECU could increase the revs "thinking" that the temp. is too low... if you dont have tester to read live data you better just replace this one... it's cheap enough and if it was good at least you have a spare for both coolant temp and fuel temp sensors cos they are the same.
