Sounds like a wire arcing.
I bet a wire isn't all the way on.

ok wait, lol i just remembered that i didnt have the #8 coil pack connected, would that cause this? i was only moving the car from the driveway to the front of my house 10ft when i saw the ses light flashing completely freaked out and didnt remember the coil pack being disconnected at all.

White normally means lean.
Which would be odd for a near stock or stock car since the computer normally has them running rich a little bit.

okay i did it finally got #8, the car runs 10times smoother, i couldnt believe it i could hardly tell the engine was running (exhaust gave it away) yea i was thinking the white plugs were kinda weird, they were denso plugs or somthing like that. are those the stockers? i did have the slp power tune(from the diablo tuner) programmed on the car for a little bit, 3000 miles, would that do it.

Yes it would.
They tend to lean you out a little to gain power.
