Re: Weak spark
Swap Spark Plugs with a different Cylinder and see if there is any change.
If no change then look at:
...Ignition Wire #1 resistance?
...Distributor Cap Corrosion inside at Contact for #1 Cylinder?

Re: Weak spark
SWAP means interchange. See if the problem moves.
Did you look at the plug for the proper gap? If you, or someone else dropped it, then it will not function as designed.
If you got a little too crooked with the spark plug socket, then you might have cracked the porcelain.
And NEW does not automatically mean GOOD.
