Awhile ago i hit a curb with my car on the passenger side. Its the left side of my car (JDM import). After that accident my tachometer wouldnt register, actually it sits below zero! however, my speedo still works. When the car's rpm's go high enough then the tach seems to start moving. but it obviously isnt registering at the correct rpm.
I'm wondering if a cable came loose or where i should begin to start looking to fix this problem.
has anyone else had this happen to them?
