strobe light check guages
A scan tool may be helpful in isolating which cylinder is the problem.

Never seen that one before... The check gauges light comes on when one of the dash gauges is out of range, and my guess is that Tunafish is right, you tweaked the coolant temp sensor (or wiring) and it's intermittently shorting/opening. (That's a likely scenario right after a wire swap).
Do you have access to a scan tool ? The factory temp gauge may be too slow to respond and you can't see the rapid changes caused by the shorted sensor. Does the car stumble at all when the light happens ? A messed up temp sensor will mess up your fueling and the car will sometimes stumble...
Just a guess, could be completely off-base here...

turned out to be faulty knock sensors. coolant was getting to them. once i replaced them, problem solved.
i took off alll the wires again and actually put dielectric greese on them all, no change. :/
. I would assume if it is flickering at idle, it is because the alt is just barely putting out enough, if you rev it and it goes off it is because the alt is putting out a bit more and keeping it happy. Check the wires going to the alt. also- as mentioned, they run right in front of the head there and it is possible something happened there.That's my take on it.
