So i diagnosed my 2003 with the rattling noise caused by a faulty intake manifold. At first i thought it was my serpentine belt because toyota told me i should get it replaced when i went in for an oil change but then i started to search and read about this problem. I'm guessing its the intake manifold because its described as a rattling noise at idle that gets louder when you accerlate and thats what i'm getting. I'm sure some of you have seen or heard about this issue. Anyways i have read in some places that this is covered under the 5yr/60000 powertrain warranty. Anybody know this for sure? I've seen mixed comments on it. It is really expensive to replace out of the pocket. Ranging anywhere from $500-$700. So getting it done under warranty would be a whole lot better. I need answers soon because im at 58800 miles right now! Thanks in advance!
