2.5L pinging
Looking for help with bad pinging at acceleration. have a 2000 mazda B2500 [Ford Ranger] 168k, all tune up items and filters replaced, timing belt replaced, good fuel pressure, no faults, seafoamed at; booster, crankcase and tank, gets @ 25mpg, good acceleration, replaced EGR; actuator motor, valve and exhaust press sensor. Still pings with premium gas and octane boost. Checked timing = 6 BTDC at idle, does jump to 30+ when rev engine. As best I know timing cannot be adjusted. Any suggestions would be greatly appreciated ! Thanks
