Engine

Its been a while since i posted as after the Cinq failed the MOT the second time on emissions again i changed a few more bits and somehow managed to make it far worse than it was! After swapping a few more sensors and injection body gaskets i had an issue that for no reason the car would constantly rev up and down when it was idling (it seemed fine when driving, apart from a little lacking in power) and if you had been going along and stopped at a junction, the revs would jump straight up to about 3’000!…
