I bought this car a few months ago, and had overheating problems. So I took it to the Honda Dealership, and they diagnosed a Blown Head Gasket. So they replaced the head gaskets, water pump, thermostat, timing belt, head bolts, and all the other intake gaskets. So I picked my car up the other day and drove it home and I had no problems at all, everything worked fine.
The same night when I took it out for a drive WITH THE LIGHTS ON I noticed after about 10 minutes of driving that the Speedometer started acting crazy, and after a while it just stayed at 0mph, and when it did this the odometer stopped moving too. So I tried to adjust the Light Switch that controls the brightness of the Instrument Panel, and if I keep the switch at one extreme the speedometer stays at 0mph but if I keep it at the other extreme the speedometer stays at 140mph and the odometer moves like it is going that speed, even if I am parked.
I do not have this problem when I am driving around in the day with the lights off, unless I like try to use my power windows or something, and then the speedometer jumps a little bit and comes back to the normal speed. Also yesterday when I was driving on the highway with the lights on I did not have any fluctuation with the speedometer.
So my questions are:
1). Does this have anything to do with the dealership's work on the BHG ?
2). Could this be a bad Speed Sensor ?
3). If it is why does it only fluctuate when the lights are on ?
4). If it isnt what could it be ?
5). Why do you think that it doesnt fluctuate when I go at a constant high speed ?
I am sorry I am asking so many questions, its just that I have spent almost $2000 on the whole BHG job, and now this problem, just frustrated. It is a great car, and I want it to last.
sounds like some wires got crossed up when they did the head i would just take it back and tell them might also just be a bad ground somewhere which could also be from the head work
