What did I do wrong?
I changed my plugs and wires several weeks ago and I am still not sure what is up. Long story short, I used ngk tr5ix plugs gapped @ .040-.042 and my second set of wires are a standard set from oreillys. I had trouble with the plugs vibrating lose already, but I went back through and re-set each one. Now car runs ok and I have been driving, but just doesn't seem to have as much power and at times I swear it's going to start idling too low. Could the gap be too narrow, did I still not get them tight enough (I doubt), or anything else. I am really pissed that I didn't IMPROVE the cars performance.

I only have a catback and air lid. All else bone stock. I searched on here for a while and found the ngks to be favorite and thought the iridium would be a good upgrade. I also found that the gap people use varied greatly, and even oreillys had a few different specs.
