Got a bad miss

Possible bad coolant temp sensor telling ECU wrong engine temp and thus ECU sending wrong injector pulse.

you don`t say how you verified that the plug and wire was good. I think these use coil on plug, if so check powers and grounds for that coil as one may have a problem.other things that could cause this is a bad fuel injector, poor compression due to either rings, valve, worn cam, damaged push rod,

Check your cat. converter on the exhaust. Start engine and using a rag (so you don't burn yourself) block the tailpipe and how much pressure is coming out. If it seems to take some time to build up the converter could be plugged. Next disconnect the exhaust at the engine tie up the exhaust so it won't drag and road test. If the converter is bad the engine will run normal if still runs the same then you will need the electronics checked out.

bad throttle position sensor

You either have a really bad COP Ignition Coil,
or you have several failed at one time.

If you have a professional scan tool or software used, in
Generic Mode $06, you will see the individual cylinder
misfire counts. Then you can replace just the bad guys

If your front two O2 Sensors have 100,000 miles on them,
replace those two. Unrelated, but you will notice the instant
throttle response,once you get rid of the misfires

Also need the correct spark plugs,not fancy ones with several
prongs,they don't work in that car

I suggest NGK Double Platinum ,the Single Platinum were the
OEM made by NGK

Don't be supprised if the Battery goes dead & causes those issues
also. Have to go to a Dealer for that,because of the vent out of the
trunk. (BXT-66-750) $109.95 ,no discount, even to a business,
just got one last week

Give me the codes you have & if you have the ETC Failsafe lite
Does the MIL Lamp stay on or flash? If it flashes don't use the car
you will ruin the converter

Bad starter or starter power connection (positive lead) also check your Flywheel for missing teeth after you get the starter out!

it sounds like a spark plug is bad try putting in new plugs it should fix it

Don't think it's missing. Low fuel. Check fuel pressure after regulator.

How did you inspect your parts. Sometimes a part might look ok when actually it is bad. When was the last time you replaced your Fuel filter? I would perform a fuel pressure test. You may have a weak fuel pump. You don't list checking your plug wires. You may have some bad plug wires. Also remove your rotor and look in the distributor. There is a part located under where the rotor goes that is a ceramic type of material. I can't remember what they call it but inspect it for cracking. Is is a fairly common thing. If you see cracking you will need to replace the distrubutor shaft which is not a big deal or you can buy a remanned distributor if you don't want to mess with it. Also you may have an EGR valve that is sticking open which could cause your symptoms.

HI. One way to check which injector has the open circuit is to use an ohm meter.
With engine off disconnect each injector at a time and put the test leads of the ohm meter on the terminals of the injector, take a reading. The 4 readings should be approx. the same.
The injector at fault will show no reading ( open circuit)
So good luck with this test
Ps if you don`t have an ohm meter they are cheap to buy. you don`t need a profesional one
