Having problems with your 2000 Mercury Cougar ?

My 2000 (V plate) Ford cougar 2.0L zetec failed its mot today on Exhaust emissions. My readings are as follows Fast idle test co = 0.21% = pass (max 0.30%) hc = 36 ppm = pass (max 200) Natural idle test co = 0.54% = Fail (max 0.50%) the car had a new cat fitted around 6months ago along with new ht leads. Any idea's to get that 0.04% drop in idle would be great!
