My 1997 Maxima runs very well, having almost 365k.
Lately the tachometer has been sticky getting into first gear, and then it seems to run higher at highway speeds. At 55-60 mph it will be about 3000rpm. At 60-65 it will approach 3500. It will jump back down going down hill. I am in the northeast, but in flat roads and warmer temps (when driven down south), it seems to behave more normally with intermittent spikes.
I would normally get 400-449 miles on a tank, but if I need to stay at highway speeds, I can only get about 300-340 miles.
Could this be temp/load relalted? The temp guage is normal and the heater is fine. I had oil, gas and fuel filters changed, and a transmission flush.
