2000 Prelude 90k miles, 5 spd.

Im getting a weird crunching/knocking noise from the front of the car. One of the times it seems to happen is decelerating right after accelerating while in 1, 2 or 3 gear. I have a bad 02 sensor as well. Any ideas?

 

bushings most likely, what kind of service has recently been done?

 

nothing recently that might have caused it.. do you know what bushings?

 

Check your front and rear motor mounts

 

motor mounts was my first guess.. im pretty sure it only happens when im in gear. nothing in neutral.
