Hi all i got a 2002 ba falcon with 219 000ks on it and in the last week or so i have noticed that it has a tappet noise on 1 cylinder, When i hear the tappet noise directly after i hear the tap the engine miss's then runs good till it hits that tappet again, ive taken it to ford they said it was nothing and did a service on it and charge me a fortune, now im also starting to lose power and it is doing it worse since ford touched it, Also since ford touched it i have noticed it is begining to idle ruff

If anyone could please give me some advice on this it would by muchly appriciated

Firstly stop with the since you did this since you did that.
It never gets you anywhere, you're much better off asking rather then blaming.
What did ford do? Service as in just a Lube service? Did they wash your engine bay?

they did engine oil gearbox diff, coolant, also they replaced the plugs, also they gave the car a bath, not sure if engine bay was done it doesnt look cleaner but might have
