I need your help with my Rover 416 P-reg. It has an idle tickover at 1500rev (initial start up) and has an 'over-rev' problem when Im driving. It happens when I need extra power to overtake or when I change up a gear e.g. @ 50mph from 4th into 5th it went up to 5500rev then back to normal again. Its almost like it sticks, over revs then returns to normal. Sorry if I dont know the correct terms but Im trying to explain it as I experience it.
usually caused by a sticking throttle body , they used to be plastic (whicn yours probably is by the sounds of things )but are now modified and made from metal , you'll need this set up by a rover dealer after replacement
