hi guys im new here and have just 1 small fault with my corsa c20let .
the trouble is the car will not idle tidy and stays at 1.5 instead of just under 1 iv replaced the icv twice the first time it went worse up too 2k and the second time it was fine for about a mile running sweat and then back to its normal 1.5 doing my head in now can any1 help with this .
at the moment iv clamp the icv pipe to get it to hold a 1 or just under but this is just masking the fault any help will be grate

make sure the icv has the right plug connected, not the knock sensor plug

checked all these air leaks all new gaskit on thottle body .
no it as been done for a while it was not doing this when i got it well not as bad tryed to swop the knock sensor for icv but it made the engine management light come on im all out of idears now icv worked for a mile it was not new thou but come off a 100% working engine totaly lost ckeck everything and still no luck im wouldering if its worth buying a brand new icv but they are 65 pound and woulder if il be wasting my moneys 
iv not tryed the tps but have losened it and played with it but made no difference
wot as got me is when i clamp the pipe it sorts the fault out
