need a bit of help rearly ive got a 1 liter 3cylinder corsa as a dayly smoker!
as of last week the idle has gone shit (just refuses 2 idle) and when driving half way though the revs it hesitates (like u have run into a brick wall) then after a second or 2 it clears and ur off again!

so far ive checked the plugs, coil pack, and airmass but all these seem fine??
any idears would be more than welcome

thanks inadvance!
