I've posted this issue in another post about changing Plug #8, but I thought I might catch more attention if I made it a post of its own. As mentioned, I just changed out all of my Plugs. 7 on Monday eve, and #8 last night. I also cleaned and re-oiled the Holley Powershot filter. This morning on my way to work, the Check Engine light comes on, but with my recent Header/Cam install I've thrown a few codes, so I didn't worry too much about it. But whenever I accelerated on the highway the Check Engine light would begin flashing. When I got to work, I checked the filter/Lid setup to make sure that nothing was amuck there...it was just fine. Obviously after the drive in, the plugs and such were too hot to check, not to mention it was still dark. Could I have possibly not put the plug wire on tight enough? Any thoughts on what this code might be? I also re-installed my fuel rail covers...is there a possibility that I disconnected something in putting them back in? They can be a pain installing at times...just grasping at anything at this point.
Please let me know what you guys think, and if anyone has any information on the "Flashing" Check Engine light...that would be great too!!!

Check your plug wires, a flashing SES is misfires and since it started after plug change, check the conn to the coils and to the plugs.

It's generally misfire related as previously mentioned. Do you notice a perfectly timed stumble, I.E. misfire?
If the plug that drives the coils is plugged in and fine, then check the plug wires themselves.
Other than that, perhaps you cracked a plug (the porcelain part) when you installed it without you knowing.

A flashing SES is emmissions related. Normally it means the car is running rich or has an O2 problem. You may have put too much oil on the holly filter and gotten the excess on the MAF...
