I recently bought a 1990 honda accord for the winter. And for some strange reason when the car hit 72 mph or higher, the RPM needle starts going crazy. When under 72mph, the RPM needle will stay steady between the 2 and half and 3 mark. But as soon as I start going like 73 to 80 mph, my needle RPM will start bouncing around back and fourth while climing all the way up to 4 and half and even 5 on the RPM gauge. It looks to be reving the engine too high and it is not normal. I think usually if it is workign correctly, even at 80mph, the RPM should be around 3 or 3 and half or so on the RPM and not bouncing around back and fourth and climb as high as that.
It kind of sound like maybe the timing is off on the timing belt or something to me but I am not sure. Not sure when the last time the timing belt was changed. The car has about 197 thousand miles on the engine. Anyone have any thoughts or inputs?
Thanks....
