I am hoping there just dirty bec. when driving it purrrrs is it possible that the injectors are going bad and have problems when ideling and not when in drive and running it seems that when in drive holding the break it idels at like 800rpms nd its fine but when in park it idels at 900 befor i replaced my Vp it ideled at 800 in park and it did the poping just every once in awhile maybe once every five min. but since the new vp it has grad. gotten worse its wierdin me out

I am not quite sure what your noise is of course; but I do know that there has been much talk about similar issues on the various forums for years now with the second gens that don't idle quite right and make some slightly strange noises. I have followed them closely for years, only to conclude that although no one has any real clue as to why it happens, it does. However it does not seem to affect anything related to performance or longevity of the truck. I remember reading about this stuff when the 2nd gens were brand new and still under warranty and can't really recall hearing any horror stories due to the problem. Of course I am not sure you are describing the same issue I am thinking of, but something tells me it could well be the case.
I would recommend paying attention to this to make sure things don't get any worse, but I wouldn't lose any sleep over it if I were you. :c:

Howes Meaner Cleaner works good to.

While some are definitely better than others (and I won't name names), I really do think it's more a matter of personal preference than anything else. :tu:

ok thats cool Yea the noise aint loud and you can barely here it in the cab but its like a miss simple as that its a low sound pop fast and one after another it didnt do it very often and i guess since i put a new raptor 150 on and new vp tht its working right and has more pressure or better yet its working right lol and since then it has slightly gotten worse i will try to get video and put it on youtube for people to hear

run 1 oz per gallon of 2 stoke through it. it will help clean and lube the pump

its just like a hick up

ok that sounds good maybe it just needs a good lube

if you want to keep your stockers. pull them out, remove the nozzles, clean them up real good, pop test them, and put them. :tu:

yeah, im willing to bet you have a leaking injector. if you have a heat gun you can hit the exaust manifold in each cylinder. (look for the hot one)

i ran a 1oz: 1gal of 2 cycle oil for 3 tanks, but it didnt help my injectors any. i hope you have better luck than me.

yea if the oil and cleaner dont work i will prolly just buy some injectors bec. i only have one vehical right now and the nearest diesel shop is about 2 and half hors away and the fact that i am so tight on money right now
