I'm at 134,500 miles and just changed out the original plugs and wires.

Everything is original and it perfect working order other than new michelin tires, e3 plugs, and K&N air filter. Oh wait, sorry, the two little lights that light up my two front window switches are out. LOL Hardly noticeable.

I wish I could figure out why it has a rough idle sometimes, but once I get going it's perfect. I think it may need a SeaFoam treatment. Cleaned the MAF and TB to no avail.
E3 plugs = FAIL! Put Delco platinums back in and I bet your idle issue goes away. AC Delco, not autolight, not champion, not bosch. GM's hate anything but Delco platinums.

Correct, what I am saying is there is a possibility, at your mileage, you had a plug or two that may have been carbon tracked and caused the idle condition. You did install new plugs which would normally correct the concern but, again, because they are not Delco platinums, may be causing the same issue. I rarely see light idle misfires on coil on plug that isn't caused by a spark plug issue.

Yes... but I think the AcDelco platinums are at least that... they may be over 6 bux now too!
