i took my car for a diagnostic... they said im having problems with my EGR Flow Sensor and also my o2 sensor.. i have a 1997 acura 3.0 cl with 104 thousand miles on it... how do this sensors affect my car ? also what would you recommend i do to get my car running nice, and also where can i get this sensors cheap on the internet if possible then have them installed by a mechanic, so i only pay labor, my check engine light is on.

 

also my car sometimes is like im driving it slow right and then all of a sudden it kinda slows down by itself and then pick ups up fast what could be this problem.

 

but like it drops gears i dont know is weird all of a sudden just picks up like crazy without me doing anything
