strobe light check guages my check guages light just started flashing after i replaced my sparkplug wires. it flashes like a strobe light, and does it mostly at low rpm and idling, when im cruising along it doesnt do it as much. all guages read perfectly fine. any ideas?

A scan tool may be helpful in isolating which cylinder is the problem.

new to me is the oil pressure low causing light to flicker,also the temp sensor is close to # spark plug make sure you didnt unplug or break it! the alternator excite wire is in the same harness that runs down the front of the head and is fragile...do any of your gauges seem screwed??

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...

hrm i hope its not the knock sensors but very possible, how much do those cost?
i took off alll the wires again and actually put dielectric greese on them all, no change. :/

ok update today, my voltage guage will dip up and down below 13 to just past 13 while im sitting at a light. my lights and everything dim a little when this happens. also if i put a slight rpm on it with the gas pedal, it stabilizes just above 13. think my alternator is going bad? belt? cheap tiny azz wire going to alternator bad? bad ground? thanks for the help.

Take it somewhere that does free charging systems checks (AutoZone, Advance, etc.) and see. I know I got my alt. wet while cleaning my engine compartment and the regulator was messing up- the volt gauge would go into the red as I revved it and check gauges light would flicker like you describe as it was approaching the "not good" area . 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.
