It started today after driving the car for about 45min.I came to a stop light it ran fine then the tach jumped down 100rpm,the car jerked alittle.Then it went right back to normal.It did it one time at the next stop light too.Only once at each stop light and them back to normal.I got it home asap,I checked over the carb didn't see anything wrong I checked the voltage all good.It is a little cold out and the car seems to being a little more rich then it dose when it's warmer out.
What do you think it could be?
I hope it's the ignitor again. 
I did by pass my resistor wire this summer,so i had full volts to the coil.Like the ignitor insturtions called for.

New wires the Ford 9mm wires,new MSD cap and rotor.I'll get some new plugs and try that.If it's still there I'll have to take the wires back.I drove the car for about 2 hours since I've put the new wires on.Today was the 1st day I've noticed anything. How about the COIL,and if you were to change coils what would you run? And what do you think about using the PERTRONIX II coil with my IgnitorII unit.I'm still using the 3 year old Pertronix I coil.

How do I test the plug wires?

How gentle or hard was the stop at the red lights/stop signs? If it were a kinda hard/fast stop, might be dumping a little fuel over from the rear bowl.Possibly the rear float set a little too high and with out the plastic vent whisle, it is allowing a little fuel to spill over? Once it burns off, the car runs fine? Just a thought.

True. If it was junk in the fuel system, which has happened to me, you'd have goofy crap happening whether you were stopped at an idle or blasting along at 70.

It was an easy stop,I was just cruising around town.
I did notice when I got home I took the engine to 2500rpm and held it there,it missed once and then it seem to run just fine.I let it run for about 5min after that it didn't do it again. SCOOP

That sounds like a spark plug getting loaded up, then clearing out when you ran it at 2500. Look for the fuzzy plug. ------------------

Next week I'll change all the plugs and see if any look bad. Also how do you test plug wires?
It seems funny that it didn't do 2 weeks ago when I changed the cap and wires.Could a wire have gone bad after driving it a couple of times. Also the gas in it is about 3weeks old too.And it was starting to get low? SCOOP

SCOOP, To test your sparkplug wires: - Get a hold of an Ohm-Volt Meter (OVM). - Dial the scale to 0 to 10,000 ohms. - Remove the wire & place one plug wire terminal on each end of the two leads off the OVM. Read the scale. - Longer wires will read more than shorter wires. - If you have any that read over 10,000 ohms, I'd look at replacing them. - Good (expensive) SP wires are less than 500 ohms. Hope this helps!

Thanks Ryan I knew the test was done with a OHM meter but I had no idea what readings were good or not.SCOOP ------------------
