Engine Problem

[wigan_sinker]

Good Morning

I am having a slight problem with my 1.6Td in my T25 "Little Blue"

The throttle was sticking, so after abit of research I replaced the throttle cable, and all seemed fine.

I have noticed an 'actuator' type thing ontop of the engine, which seems to be sticking open causing the revs to remain high after a period of 3/4 throttle i.e. on the motorway. After 20-30 seconds or so the revs creep back down.

At first i thought the vacuum pipe ontop might have been worn, so i replaced it, but i am still getting the problem, which only seems to happen when the engine is warm

1st questions, what is the actuator type thing called
2nd, is it serviceable?

2, generaly no, although ive bodged mine to work [involves cutting the can open!!]
