*UPDATE*
Last night in chat, member RareGMfan sent me to a link to trace down an engine miss.
First step called for a cylinder check by unplugging each injector to determine which cylinders were affected.
Cylinders 1, 3, and 5 checked out.
4 and 6 I couldn't get unplugged on my short lunch break.
Unplugging number 2 yielded no change in the way the engine was running. This is the same spark plug that had quite a bit of oil on it when I changed it, if that means anything.
I assume the coil for 2 and 5 is ok since number 5 passed the cylinder check.
Your thoughts?
Also, I noticed today that the miss didn't show up until I had been driving a bit and reached operating temperature.
