96 GT Ping?
Had car 4 months, I was getting a lot of ping on heavy acceleration using reg gas barely any ping using mid grade so I replaced the original Ford Platinum plugs (probably in there since car was new) with NGK G-Power plugs, ping still there with reg gas and again very reduced on mid grade, next I removed the octane sensor and the ping is barely noticeable even with reg fuel but is still slightly there on heavy acceleration. Also after installing the NGK's, while cruising at low speed there is a very slight engine stumble now and again. What's the consensus on these plugs and could these be the problem or a contributor? What's a good choice for plugs (stock engine) just over 84000 miles (or 136000 km).
