My car is mechanically working great. I have had an issue though were my tachometer gauge fluctuates a lot. if im cruising, it works great give it gas somewhat harsh and itll go to 0. even at an idle it will sometimes go to zero but car will stay idling the same. I have repalced the gauge cluster with no luck. it is a 99 es 4 cyl. thanks in advance. no faults in system
