strange pinging, almost detination sound.

[phillip]

This is a mustang GT 2002. with a new-ish jasper engine. less than 10k on the motor. been having some issues lately with cyl #5 so far I replaced the spark pug twice. the coil pack for that spark plug, and also ran fuel injector cleaner in the tank. Going on from those points the car misfires on start up only on cyl #5 but after a few seconds it clears itself up and runs simi fine to normal. but on acceleration i can hear a strange pinging sound not like a click from a valve, or a knock from something contacting or loose. Anyone got any ideas on what it could possibly be? Also they re used the fuel injector system. the “spark plugs and the coil packs these i have replaced like i said.” anyone got any idea’s on what could be causing this?

I would like to say its an injector, but if it where mine, I would pull the valve cover and take a look at the rocker arms and make sure you don’t have a rocker that needs adjusted.
