hi i am having a problem where when the car is in neutral a rev it up to 3000 and hold it then slowly increase the rpms it jumps from 3150 to 4000 with no pedal effort it also does this at the same rpm when im driving the car under load in a higher gear it jumps like that aswell

well your rpm wires seems like its loose..check your ignitor plug..the rpm wires is the gray one.
