Engine Performance problem
2001 Honda Prelude 4 cyl Front Wheel Drive Manual 150km miles
I recently decided to get my timing belt and water pump change over with. I've noticed after the change the car sounds way different it's louder and around 2500rpms and up the exhaust note is much deeper and rougher sounding then before.
I took it back to my mechanic and he took it for a test ride and told me nothing sounded out of the ordinary and the new different sound may just be because the parts are new.
I don't quite understand how replacing the belt could impact the way the motor runs.
