make sure you put the coil pack on right plugs... if you didnt mark them there is a possibility that you could have put them on the wrong plugs...... the left side tricky.

bumping this to the top, I have the rough idle as well, it actually almost stalled out on me when i gave it some gas(rpms went up then went way down). My question is can I drive it with out doing any damage? I have an Advance Auto like 3 miles down the road that can check my CEL, or would they ever let me borrow the scanner?

yeah most likely sounds to me like you coil pack plugs might be swapped. ill take a picture of my plugs and wires since i have an SSV, and its alot easier noticing the cables since plenum doesnt cover most of motor. if ya wait til tomorrow afternoon, ill get you those pictures.

Lessons learned: 1)Mark anything you unplug from the engine. 2)Dont start a project you may not be able to finish by nightfall. 3) Change plugs one by one so you really wouldnt even need to mark the coil pack.

I just replaced all of mine with NGK's -11 but I swapped a plug at a time. The car has 140,000 miles and it seems that the plugs were only changed once in its lift time if at all. It did have a NGK but the electro was missing, making the gap .086. Even with the gap that big I am surprised the car ran the way that it did. Now with the new plugs in she is running much smother.
