If your engine is "pinging" on your 1992 Ford Explorer, which does not have a knock sensor to protect the engine, you have to try and find the cause of your engine "pinging" and correct the problem. My 1995 Ford Explorer RAN FINE except for some "pinging" (worse with
------------ some brands of regular unleaded than others) so my guess was carbon deposits and I just ran through a tank of gas with a 20 ounce bottle of Chevron Techron Concentrate Plus in it. It's like night and day now. I just tested it out three days ago by setting the cruise control and driving up a fairly long steep hill. It only gave 3 little pings where I used to have to back off the gas and just let the vehicle slow down as I was going up the hill to keep the engine from "pinging" some other causes of engine "pinging" are: engine running too hot,EGR system not functioning correctly, timing too far advanced,lean fuel mixture,MAF sensor dirty ,driving in too high of a gear (standard transmission) According to Goss's garage (Motorweek television show) the two main causes of engine "pinging" are carbon deposits and EGR system malfunctioning.
