I have a dodge intrepid 2000, one night the light panel starts to fluctuate in intensity when we start to drive. So we quit driving it. Next time I start the engine and notice the engine tend to vibrate when the rpm is around 3900. Any hints about this ?

The voltage stays within the 13.5 to 14 range when the lights and heater fans are turn on. The real concern is the vibration when rpm reaches 3800-to 3900.
