Noticed like 5 min's ago that there seems to be a ping ping ping noise coming from what im guessing is in the head when running. Could this be a injecter rattle?? Or some thing else going on, it doesent seem to be a metal to metal contact either, it almost makes a musical note lol thats a weird analogy. any suggestions

 

Mine does the same thing when it's cold, could be injector or timing rattle, your Bullydog probally advances the timing. I notice mine alot more on the cold mornings. Hopefully that answers your question, anyone with a better suggestion or answer please chime in. Take it easy, I'm from Leth. too.

 

Thats possibly whats going on, but i can hear it while at light throttle aswell. After engine is warmed up i can hear it but not as loud as on first start up. Thats cool your from Deathbridge too, ill have to look out for ya...

 

yeah my truck does it to glade to know not the only one ive got the bully dog pmt i noticed mine doing it when i stoped at a light or at idle the way i fixed mine is if u have the pmt or something comperable enable u d fueling setting it shuts off ur chip for a while tell u truck cool back down to bout 195 or so an the injector will stop rattling around its gets about anoying *** **** when it startsing getting cold but i havent noticed anywhite smoke or damge done so it must just be one of those things
