hi all , i have a 1 second delay in returning to idle on my 1.8 lx petrol . once returned to 800/850 rpm it will idle all day long without any change,but as soon as you blip the throttle ,you get the delay again.when driving there seems to be no problem but if you dip the cluch the same thing happens then it returns to normal again . would appreciate any ideas / suggestions .
cheers
