A flashing check engine light is a critical indicator. That usually means that something went wrong that will damage the emission control system... and that is usually an ignition issue. First off, the OEM plug your car calls for is an NGK irridium... NOT BOSCH and not anything with more than 1 prong. Those NGKs are like 2 bucks and they are the proper plug. Make sure you have these plugs and make sure they are gapped to .028. Next, my suggestion is put all the new stuff on again. Drive it to autozone and have them delete all the codes. Drive it around until the check engine light comes on again, then immediately go back and read the codes. The ECU is smart enough to know which cylinder is misfiring. On these cars, I think they have three banks of two... meaning one "coil" inside the coil pack operates two of the cylinders. So if you get multiple misfires, it's the coil. If you get one misfire it's probably an individual plug wire or plug. Good luck.

Random engine misfire is very hard to diagnose as there are alot of things that can cause this. I would check the PCV system first replace the pcv valve and inspect all lines going to the pcv valve for leaks. The other thing to do is replace the gas cap as this can also cause the code. Most likely cause is a fault in the emissions system.

A misfire doesn't always have to be ignition... it's just the most common cause. Faulty or plugged injector, low compression. You need to check fuel pressure and test the fuel injector flow. Then check compression. If you don't have tools for these tests, take it to someone who does. Testing is much cheaper than throwing parts at the problem.

the icm, coil, and crank sensor all read off the opti. Chances are you have a bad optispark (distributor). I just went thru the same issue and found it to be the problem.
check your fuel pressure as well, you may have anissue with your fuel pump and or relay
