Yes, coil packs send the 'spark' to the spark plugs, the HT leads are just the 'wires' carrying the electricity between the two.I have only done the TPS reset as I am a novice when it comes to cars.
Last night however, after the car was left for 3 days, it felt what I can only discribe as "lumpy" on startup. Again got to the first major junction and it stalled when coming to a full stop. 5 mins later after it had warmed up it was super smooth etc and didn't miss a beat as per usual.
Getting a service in a few weeks, going to get the garage to change the HT spark plug leads and check sensors to see if this helps.
Novice Question: Are the "coil packs" different to the HT leads?
