Yeah, it ran fine at first... But at first I did have two plugs crossed, maybe this allowed it to idle?

BTW: I had problems all along. My BLM's were split majorly in both directions. I was getting 108 blm's on the right and 160 on the left. ALL plugs were pitch black except for #3 which was white (#3 and #5 wires were switched at opti). Now after they are all in their right spot this happens. I don't think that the car was ever running "good", i tried taking it around the block when it was stable and crossed plugs and it had no power really, felt like a 4 cylinder.

 

looks like i am going to dive into the motor again... Never saw this coming!

 

I know this may sound stupid, and I may not have read through well, but have you checked your maf sensor? Mine was bad, and your symptoms sound very similar to mine on my old 94 Z28

 

i think you better log some data before you start tearin into it! if your car ran fine before then something has happened and it could be really easy to fix. get a datamaster file and let some guys look at it.. id like to take a look too.

is your coil wire good and tight?

 

LOL, this may sound real stupid but I'll say it anyway. If it ran right before, and then you switched two plug wires, and it runs crappy now.... are you sure those wires were crossed?

 

No, The car started acting bad even with those two wires crossed for a while, i have had two un related problems. Now that the plugs were fixed the cars seems to run a little better but not much. Headers are still glowing etc.
