38k miles, second set of replacement NGK copper plugs. about 5,000 trouble-free miles on them without incident, then I start getting lag. it's worst around 4,000 and at 4,800 it's like I hit the VTEC cutover as all the power comes back.
it is 100% gone if I reset the ECU and has been happening for about 1,500 miles. since a second reset and oil change 500 miles ago, no problems. of course I don't really care right now because I have a little coolant issue. not that anyone has read that thread.
