Engine Vibrations
I just put the Denso plugs in my car and I think something is messed up. When I pull up to a stoplight, the car dips down in RPM and gives me that "I wanna stall" gasp. Also, the steering wheel seems to vibrate a bit more than it used to. Thoughts on what is going on? BTW, no engine lights are being triggered. HP gains not noticed.

Couple of things to check.
1) Make sure the plugs are gapped correctly. You shouldn't have had to change them when installed, but maybe you got one that wasn't gapped right.
2) Make sure all the plugs are seated properly.
3) make sure all the plugs are tightened properly.
4) Make sure the coil packs (plug wires) are secured and seated properly. Tighten the allen.
Other than than that, you could disconnect the positive battery terminal, resetting the ECU, then reconnect and take the car for a spin.
