my tach jerks around 1.5k to 3 k for the first 10 mins of driving,..this happens once in a while. , but it does not affect the drivability, ...its just that you see the tach needle jerking around once in awhile. does any have this problem and how to cure it.
thanks
oh yeah, when it jerks to 3 rev for example, the engine still sounds like it is idleing at 1 rev not at 3, its just the tach reads 3.

 

This could be caused by cold solder joints on the instrument printed circuit board, they tend to be thermal in nature. Try hitting the cluster when its doing it and see if the symptom changes.

 

My tach jerks around all the time, but I think its cause it is broken. I have heard that the FD does have a problem with the tach and the speedo, but I'm not sure.

 

Yup..I am still having tach problems......

 

What year is it? I don't have tach problems, and I have a 94.
