Guys i have been watching you all for a long time and its great to see what you guys have to say. I posted this question over on nloc a couple times and never really got an answer that really helped so ill talk to people who have the same truck as me. Heres whats happening it seems that sometimes i get in the truck and there is a gargling of some sort like some air or water is in a line trapped and wont come out. its real hard to explain it seems to be a slight gargling that only seems to be going on periodically and it seems only a slight throttle or idle. It seems like it comes from the firewall but im not exactly sure. I tried opening up the radiator cap or whatever and let it run but it seemed to yield no result.
Heres another question it seems sometimes that in light throttle i have another vague noise, it seems like a fluttering almost like something is vibrating but i have pulled everything out. so it most likely isnt that. it seems almost as thought the tranny is rubbing against the floorboard. again its somewhat periodic. and only in light throttle it just fluters. i have taken it to the dealer and they said it was normal but i dont think they even checked it out. lately it seems to be loosing power so im pulling all mods off and taking it to the dealer again. neither of these noises seem to happen at full throttle but they are anoying and i am tired of hearing them. any help?

 

Depending on your dealer and the relationship you have with them as to whether or not your mods have to come off for a visit

Might check that out
most dont care if nothing radical done or engine never gone into,
just bolt ons

for what it is worth
