I bought my 93 lx this past Sept. It only had 18,900 miles on it.(All original had it checked out) Well, I just turned 30,000 on it and thought it was time to change the plugs.I took them out,didnt look to bad,a little whitish.I put the new ones in,and couldnt believe the difference.Started faster "Revved" so much easier,and actaully felt a little faster! After drinking a beer and thinking about it, it dawned on me.Its a 1993,those were the "original spark plugs"!!!That should have been the first thing I changed when I bought the car.I heard a little voice in my head say YOU DOPE!!
