If there iridium plugs dont go with a wire brush at them, spray them with carb / brake cleaner thats all!

cleaned afm and spark plugs today the afmr was dirty alright but not the problem.there is a greddy type s bov on the car when i pull off the vacum hose going into it and dont block the hose it runs perfect but if i block the vacum hose or if i connect it back to the bov it starts reving up and down again.is the problem the bov or something else.also when i start the car it runs fine until i give it a rev

when you've that pipe off and your thumb on it, thats the exact same as when its connected, there would be no air flowing in that pipe during idle when its connected to the bov,

sounds like its running rich and when you give it more air by letting it into that vacuum hose it runs better, could be wrong on this bit???

anyone any other suggestions or any more on what niall said.
was driving today and it cuts out when the revs drop say commig into a roundabout or traffic lights etc.its wrecking my head has to be something small cause was running perfect before i parked it up
