Why would you replace the computer? If the engine starts and runs the PCM is probably OK.
Instead of shotgunning the problem, why not figure out what is wrong with it and fix it?

Ok, why is it that you think that all the coils are fine?
Just because they may have been replaced doesn't mean they are all fine.
I had a similar problem and eventually.... the computer diagnostics found the bad coil and once it was replaced all was fine again.
does the diagnostics tell which cylinder is misfiring??
Swap the coils around and try again, If a different cylinder is misfiring then you've found the bad coil.
Just my thoughts.
