I replaced all of the plugs and now I'm acquiring a check engine light and it appears a bit sluggish. It runs rough at idle and slow speeds, and runs smooth, but outright gutless above 50mph. All of the cylinders are firing- I did the old, pull the wire off and see if the idle modifications test. My only thought is that I gapped the plugs too large and it is finding some inconsistent misfires. I gapped according to the .060 specification however, I noticed that the old plugs had been gapped around .055. Really should I re-gap to a different spec, if so, what really should it be? I'd like to get some guidance ahead of I go back and redo every thing . . . those back 3 plugs are a discomfort in the butt!
Thanks, everyone, for the quick response. I'll let you know how it pans out . . .
Very best answer:

AC Delco or any quality spark plug replacement really should have been pre-gapped and required no gapping, particularly for newer platinum kind plugs. Make sure you bought the exact parts replacement for your vehicle. Physically bending the electrode could damage the plug.
