When i used to hit vtec(5200 rpm) in my 2000 civic the car would kinda jump(go faster kinda) in a way and I could hear it kick in but I noticed yesterday that when it hits 5200 rpm I cant hear it kick in and the car kinda bogs in a way in that area. Is my vtec sensor gone bad? Is there any way to test besides not hearing it kick in.

 

When was the last time you did a tune up?

 

heres how to test your vtec solenoid
