I had a bit of a rev hang problem with my 5ltr - turned out it was the cruise control cable holding the throttle open - it was accelerating by itself while driving and was sitting at around 2700rpm. All I did was disconnect the cruise but im gettin it fixed on wednsday . . . Hope that helps somewhat
Cheers Grant |

300kpa is too much fuel pressure with a standard ECU map, especially with a cam.
Make sure the base idle is set correctly, the oxy and PS sensors are working, the ECU is throwing no codes, etc.
