I have a 1986 Accord LX (carbureted), manual, with 315,000 kms. The car has been in our family since the dealership and has always performed very well.

There has been a recurring problem however when driving the car on highways at high elevation. When it is driven above approximately 3000�, there is almost always a sudden drop in power. This loss of power generally lasts for 10 minutes at which point power is immediately recovered and the car operates perfectly. It is so severe that I must often shift down to 2nd to climb large hills, which needless to say is dangerous on the highway. Furthermore, even when driving down a gentle slope, hitting the gas makes the car jerk momentarily and then continue to gradually lose speed.

I have taken this car to several garages and they have failed to pinpoint the problem. As it is related to altitude, I can�t help but figure it is due to the carb (I have tried cleaning it using some basic sprays and such with no effect). I�ve ran the car with both full and nearly empty tanks and the result is also the same. Any further recommendations would be greatly appreciated.

Thanks,
Mike
