Hey guys
Just came back from taking my dc5 for its MOT it failed because the engine was hunting/seeking with its revs which means that an emmisions test couldn't be carried out.
It revs from 1500 up to about 3500, and when driving isn't noticably happening, when stationary it will then hunt/seek. I've given it some beans (kept to speed limit but was revving the engine more that normal) on the way home and since putting it on my drive it seems to have settled at around 1100-1400 revs, which is fine to carry out an emissions test as it needs to be below 1500 revs but from what i've read on the forums this is quite high as others seem to idle around 800-900 revs.
I have had the airbox removed and a Cold air induction kit installed, apart from that nothing else has been done to the car. She has been off road for a month and a half and the battery ran flat so i had a mate jump (with jump leads) her, she didn't start straight away but on the 2nd attempt (5 seconds of cranking each) she started and was running fine at about 1600 revs on a cold start cycle, after the jump leads were taken off and the cold cycle ended she then started hunting, i thought this was because of the low battery, turns out this isn't the case as i've had a new battery installed.
i've also found that when parked up and car warm i can't push her into the v-tec is this normal as i can't seem to remember this happening to me before, she seems to go into the v-tec fine when driving.
i think it could be a vacuum problem, but any advice would be great
cheers
