depends upon what make and the size of the engine.
second coil pack back from the front on passenger side
1-----2-----3 4-----5-----6 front of Ford Escape ( with V6 engine )
what is the number coil pack
On the 4.2 L I6 the very front of the engine is #1 and the last in the back is #6
It is probably the coil pack. To find out for sure remove the coil pack from number three and switch it with the coil pack from number four. Run the engine for awhile until the light comes back. If the new code shows that the problem has moved to number three, you know that coil pack is bad. Otherwise it is probably the wire or wire connector going to the coil pack or possibly a bad spark plug. Good luck

Here is the number three coil pack located?
what side is the number one cylinder? is it the right front?
The firing order is irrelevant. The coil packs are numbered from One to Six starting from the front of the engine to the back. A misfire on #4 cylinder would be the fourth coil pack/spark plug from the front starting nearest the radiator for #1.4 is common, as water can leak from a bad hood seal onto the coil pack, especially if parked with the front sloped forward.
you have to remove the coil pack, that is blocking you from getting to the odd numbered plugs. there are a total of 4 bolts that hold the coil pack in place. 2 on the front, and 2 in the back, which are very difficult to get off.
