If it is missfireing it wasn't your starter coils for a start. A reason your car will missfire is the timing is out. If it starts and runs your timing maybe a 1/2 a degree out and needs adjusting. It may also be one or more of your ignition leads (from spark plug to coils). Easy way to tell is with a timing light just plug leads in one at a time and start your car if timing lamp doesnot light or lights only as missfires change your leads, check your timing also while you are plugged into number 1 spark plug put timing light onto crank shaft pully should light up as a white dot goes past (bottom pully wheel). If you don't have access to timing light you can manually do it just take number one spark plug out with a small but longish screwdriver(careful not to dint or scratch piston head) crank motor by hand useing bottom pully till number one pot is to the top and look at bottom pully if white dot not at top crank motor till pot comes up second time and check pully wheel again. If still dot not on top your timing is out and you need to adjust it. If you find it to be your timing leave me message and tell me if fuel injected or carbureted and if you have magneto or distributer and I will try to help you
misfire caused by leaking in the intake valve you must chek it , or may be your car is working rich that means fuel - air mixture is not on the right ratio so check your oxygen sensor
SOURCE: 6th cylinder misfire. replaced spark plug and
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

Plugs get changed at 70,000 miles
I would suggest that you use the OEM
Plugs,they are made by NGK and are special
on my 2004 LS,I don't know about yours.
Clean the MAF Sensor with the CRC Product
for that
Change the 2 front O2 Sensors at 100,000 miles
Check fuel pressure at the fuel rail on engine
The coil you replaced on #6 ,even though you
have a PO306 Code,doesn't mean that was the
bad one. It is a COP Coil or Ford thing, you will
learn as you get involved with them
In some cases, you buy 1 new coil and walk it
from one cylinder to the next.
On single coil codes, you may get lucky,on multiple
codes or a really bad coil you won't
Your not using any fancy test equipment and
unfortunately a lot of repair shops have it and
don't know how to use it,including dealers
V6 or V8 ?

THE FUN I HAD WITH THESE RODEOS BACK IN THE DAYS. Hi Dominque Harris former master technician for izusu. These vehicle will make you spend alot of money. Stop and order yourself a ion sensing/ion sensor. that will seal the deal.
