Hi to all, new to this forum. Lots of great Info here. Here is my problem I have a 97 mountaineer with the 5.0L engine. I have to run regular Un-lead in it or it will ping. Has been that way sence new. Now it has gotten worse. It will ping on regular on any slight hill. Is there a sensor bad or is this just there nature. The truck has 250,000 miles on it.
