Ford Mondeo 2002 year Engine Missing Problem Help Needed

[britishlions]

Hi i have a ford mondeo 2002 year 2 litre model.first of all i was have problems with the tick over idel and the car was missing alot.I change the spark plugs to geniune ford ones (cost £45) and i change the leads to ford ones also(£45).i had the computer checked which brought up no faults,so i had the car check by the local injection centre.They sorted the idel tick over out and recommended i place injector cleaner within the petrol which i did.The problem with the missing is still there and its really bugging me now.it happens every now and then but still to much for me to forget.i love the car as its a ghia x model so i would like to get it sorted.I also tonight removed all the sensor conections and sprayed contact cleaner on the terminals and its still missing.the car as done 130,000 motorway miles but has full service history Can Anybody Help With Advice.
