I have a 2003 Toyota Echo with approx. 90,000 miles on it. I have had the car for 2 years now. For the past 1 1/2 years it has made a rattling/chirping noise when accelerating until it switches into the next gear. I took it to the dealership when the noise first started and they checked all the belts and tightened them. However, the problem has persisted.

I've had all the routine maintenance done and everyone that has checked the car out is unable to locate the problem. No codes have come up and neither has the check engine light.

I'm driving across country in a few weeks and I was hoping to resolve the problem before then. Please let me know if you have any idea what it might be! Thanks in advance.
