when you "tightened" the distributor, it must have messed up your ignition timing.
just like you can loosen the distributor too much, you can also tighten it too much.
most distributors on newer engines like yours will adjust themselves. however, if it is out of adjustment you can use a simple timing light.

haha agree with you there, my friend
if you're not getting spark, this does help with the possible causes, given it's not rotor, distributor cap, or ignition coil:
1. bad crankshaft position sensor
2. corroded wires to the Powertrain Control Module or Ignition Control Module
3. Bad pickup INSIDE the distributor
4. Faulty Ignition switch
I would start by inspecting for corroded wires.
