The cool pack broke and I took the spark plug out would that make it jump time

What is your question?

It has been shifting hard then it started making a load noise i checked under the hood and noticed the coil pack was broken so I checked the spark plug can I just replace that one or do I have to do all of them and what does that do to the timing

How long has your 2003 Lincoln LS had this problem?

Shifting hard over a month, cool pack breaking today
