I have noticed with my truck when I let it sit for more then 12 ish or so hours when I go to start it there is a louder then normal boom upon start up. If I daily drive it, this problem doesn't exist, nor does it come back unless the truck sits for an extended period of time.

is it possible that an injector might be leaking slightly when it sits? motor is the 3vze

thanks,
