Hey Guys,
I have had the same problem with my 98 Explorer 4x4 4.0 SOHC since new. When RPM's reach 2600 or above (even on light acceleration) the engine will ping. It used to only happen for the first 15 minutes or until the vehicle was "warmed up". then it would go away and I would notice a power increase. Now it never goes away no matter how far I drive. The symptom will also happen if the vehicle is idling and I "wrap" the throttle quick. The check engine light has never come on. Is there any way to change the engine timing or enhance it. Resetting the computer has no effect. I have tried different gas and still no change. The dealer says they cant do anything because of no error codes. The good news is that I am easy on the gas ,but merging onto the highway is nerve wracking at times. Let me know what you think.
