Question about 1997 Toyota Camry
Lately when I start up my car I hear a whirring noise from under the hood. It sounds like a loose belt or something but I just got the timing belt changed less than a year ago so it shouldn't be anywhere near worn out yet. The whirring noise is pretty loud from both inside and outside the car, particularly when it is cold, but goes away once the heat of the sun has had time to warm the hood and engine up. I am having no other issues with it. Steering is fine, braking is smooth and silent. Acceleration can be a bit sluggish, but has been that way since I bought the car.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Thank you for responding to my email regarding my car problem. Your suggestion to replace the timing belt/tensioner had nothing to do with it because they have been replaced recently and infact I may have found the problem and please correct me if I am wrong.
Well, I performed a compresion test on the engine and found out that two of the cylinders are only putting out 150psi compare to the other two which is 180psi. I also found out that these two cylinders are not firing even if they are getting fuel into them and receiving spark from the spark plug wires. You can troubleshoot this easily by pulling the spark plug wires one at a time and you should be able to tell a diffirence on the engine idle. If no change on the idle then that cylinder is not firing. Right now my car is parked and I'm rebuilding the enigine myself.

I have a 2008 Sienna with 34000 miles. I have had the same noise since it was new. I finally talked to the dealer today and was told it is the fuel injectors and that it is normal.
