sorry about that its a 3.4 v6. i know noise diag is impossible from a desk. i was hopeing the simptoms i described would help differentiate from the 3 types of noise makers. ive never heard of a lifter kind of go in and out at random. nor have i heard of shutting down the engine then restarting it have an effect on valve train. it is kinda hard to determin between the two types for me because i dont know what a snappy injecter sounds like.i am pretty good with carbed 8 cyl engines but this efi v 6 stuff is alot different. thanks for your time.
