    little problem im having with the car..

    my car idles at about 2 revs when cold.. thats fine.. when its warm it idles at just under 1... however when sitting still at lights etc.. it shudders every few seconds... there is no loss of power.. now i just noticed it has a decat and also i put octane booster in it... the car was sitting up...
