2007 Toyota Camry — buzzing noise only at one engine RPM

Don't overfit one forum story to your car. If it still isn't clear on the 2007 Toyota Camry, a specialist hour can be cheaper than another round of parts. That's where I'd start. Write the result down so the next test isn't a repeat of the last one. If the story changes I'll post the new data.

Owner notes beat generic advice here. On the 2007 Toyota Camry in Orlando, I'd fix the thing you'll notice every day before chasing spec-sheet extras. I'd do that before spending real money. On “buzzing noise only at one engine rpm,” that was the fork that mattered for me. This is from a 2007 Toyota Camry in Orlando. If they can't show the line item, I assume it's hiding. If your situation is the opposite, ignore me. I'd rather look cautious in this thread than stuck later.

I'd keep this practical. Verify the cheap/easy branch on the 2007 Toyota Camry before a big repair or a big spend. That's where I'd start. Verbal 'we'll take care of it' is not a plan. This is me being the wet blanket on purpose.

Write down what you already tried. A second data point from another 2007 Toyota Camry owner helps more than a generic diagnosis. I'd do that before spending real money. I'd want that in writing, not as a promise. If this is nothing, great. I want that in data.
