Missing on #4 plug.
When ever the 97 Ei is under load or at full throttle it'* seems to be missing on one cylinder. The aeroforce scan gauge is showing multiple misses on #4 cylinder while it'* happening. When the car is driven normally there is no notice of any problems.
So far I've done the following to #4 plug and the problem still exists.
Installed new spark plug.
Installed new ignition wire
Swapped out the coil corresponding to #4 plug
Made sure the 02 sensor wire is not close to the plug wire.
Any other suggestions?

I don't suspect a bad PCM in this case. Swapping injectors will verify if the injector is the problem. If you still have a miss after that I would pull the valve cover and insect the valve springs, you may have a damaged exhaust spring.

Update:
I replaced #4 plug wire again and will keep an eye out for any misses from the aeroforce. Mind you I'll feel it before I see it.
Thanks guys.

The only problem I see with that is why is one plug fowling up and not the others. The rear bank tends to run a tad richer then the front, but still, all 6 plugs should be about the same. If one plug is way worse then the others, you still need to find out why.

Did he post a picture of that plug? Carboned up tells me there'* fuel but bad spark, or not enough exhaust flow. I would expect low fuel but good spark to be white/gray ash build up.
