MY ENGINE PINGS UPON START-UP BUT STOPS WITHIN 5 MINUTES OF RUNNING IDLE.

2006 Mitsubishi Truck • 82,000 miles

If the engine has sat for over 20 minutes it will ping on start up for around 5 minutes. There appears to be no loss of power and the idle and acceleration is smooth. If the engine is oly shut down for a short time there is a slight ping at start up which dimineshes withen a minute.

Could ping be a lifter noise?
