Hi, I have a 2002 Corolla with about 180,000 miles that has been well maintained, but I know very little about cars.
Over the past months, I’ve noticed the engine noise on acceleration sounds a bit louder than I would expect it to, and it seems to be getting louder over time. It’s slow changing, so I’m a little unsure. And occasionally I wonder if I don’t hear a sound that shouldn’t be there, though I couldn’t describe it yet. Mechanic said the acceleration noise is normal at start-up for older cars until they get warm, but this happens even after I’ve been driving a while. Worth the $100 for an engine checkup?
Also, the A/C doesn’t seem to be the strongest and has a high pitch noise when I run it. Normal?
