OK, so having a code reader permantently attached to my car and an ipad nearby at all times has proven to be helpful.....

With these codes and, with them, a rough idle, can I expect in most cases that replacing my coils (I'll have a set of 6 here today hopefully) and, for good measure, taking my iridium plugs and swapping with Champion coppers take care of the issue?

Could it be other things? I do have a new CKPS on-route too just to have since I am told that they will go bad but would that be a good thing to replace now just while I'm under the hood or possibly exhibit these codes if bad?

Just trying to cover all bases and understand the car.

Thanks!

So a vacuum leak most likely? I won't have the coils in until the weekend at which time I was just going to replace them anyhow and keep ahold of the old as a last resort since I also wanted to replace the plugs anyhow.

I have an appointment tomorrow already set to do shocks and a-frame bushes and I hope I can convince them to fit in a vacuum test in that same time period..... not sure how available parts are same-day if needed though...
