My 93' Explorer pings on hard accelleration even with 93 octane fuel (87 makes it worse). I have cleaned the MAS (rcvd idea from this web!) which improved the situation, but didn't fix it. I have replaced the o2 sensors, and run gallons of cleaner through the engine--with no improvement. What should I check next?
I have (clean) K&N filter, Platinum plugs, Split Fire wires.
