Today I had my starter replaced in my 1995 Geo Prizm. I went to a mechanic I trust, but he works at a Honda shop and my starter was in a difficult spot so he referred me to a general mechanic. The guy took about an hour and a half to replace it and charged me $53.25.
When he was done, I noticed that when I blipped the gas in neutral, there was a metallic rattling noise from near the left front wheel as the revs came back down. I brought the mechanic out, he poked his head under the car, banged on something, and said that the ceramic something-or-other had come loose in my catalytic converter. Needing to get to class, I didn't say anything more about the subject and left.
When I got on the road, I noticed that my car made a medium-pitched whirring noise (somewhat like the sound a diesel engine makes except smoother) whenever I applied the gas in gear. Like, I would be going at 70 on the interstate with the throttle barely applied, push the throttle down, and start hearing the noise. It happens at any speed pretty much, as long as I'm applying the throttle. The sound is coming from the same location (as far as I can tell) as the metallic rattle. I can't verify the noise when the car is sitting in neutral. My engine/exhaust does seem to be a bit louder than it used to be.
I'm going to be taking my car to a mechanic when I have time, but my main question is if this noise I hear when driving is related to the catalytic converter.
