Could be Distributor Points,
Quick clean with fine file or wet&dry to see if it makes a difference.
Could be Capacitor (Condenser) across points. Distributor Cap, could be cracked or have a HV carbonised track.
Distributor Rotor Button or individual HV leads to spark plugs. Check HV leads with Ohms scale on Multimeter. Or swap lead with one of the others. Or substitute HV Lead one at a time to determine if missing spark.
Process of elimination from easiest to hardest unless you have the knowledge & tools.
Good Luck

Check the coil wire from coil to distributor cap.

There is no test for module in distributor, but they often cause this kind of problem. Also while in there, check the pickup coil wires to make sure they are intact.
SOURCE: CHANGED SPARK PLUGS NOW HESITATING & RUNS
chances are an ignition wire was damaged when you tugged on it to remove it from the old plug .. the ignition cables have a high resistance wire inside (not a solid wire) this is not hard to damage .. check to make sure each wire is properly seated on the plug .. its easy to not get it on all the way since you cant see it ..
SOURCE: PO307 check engine code. i have changed spark
Causes: A code P0307 may mean that one or more of the following has happened:
* Faulty spark plug or wire
* Faulty coil (pack)
* Faulty oxygen sensor(s)
* Faulty fuel injector
* Burned exhaust valve
* Faulty catalytic converter(s)
* Running out of fuel
* Poor compression
* Defective computer
Possible Solutions: If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
Hope this helps (remember to rate this answer).

Did u find code p0306 comes up ? Two things can cause this if the plug and coil have been replaced.the intake manifold may be leaking in the area of cyllinder 6 or its a mechanical issue.try doing a cyllinder misfire test and also check the compression on all cyllinders
