Got home and found a knock sensor code. Sensor was fried-had about 0.5 ohm resistance and potting was starting to melt. So far I've done the following with out solution:Replaced knock sensor.Clean MAF sensor.Checked vacuum at idle--good;Replaced fuel filter.Checked fuel pressure--good.Checked fuel use--climbs normally when increasing engine load above 20% where pinging begins.My next check will be EGR and plugs which are nearly new--less than a thousand miles.Note: Pinging doesn't begin until engine is fully warmed up.Any suggestions for other things to check out???
