throttle position sensor, wicked vacuum leak, or could be your lead foot mashing the gas pedal to the floor
also what you might be referring to could be a load on the engine, (such as an uphill slope) which would cause an automatic transmission to "downshift" gears to find a more powerful rpm.

nox is from exhaust temps too high or a cat. convertor breakdown.

most amplifiers have overvoltage shut off protection. verify the voltage coming into the amplifer it should be less than 14.9 volts even at high rpm
Higher octane is helpful for high compression engines. High compression causes the combustion to take place faster and can cause pinging and a loss of power. By using high octane with high compression you get the advantage of the extra efficiency of the high compression engine and the delivery of the combustion across the power stroke of the piston, with out pinging.
It sounds like the timing is set too high and needs to be lowered...
Many time the high pitched whistle will be cause by a loose or unattached vaccuum line on the engine.
no!!
Yes, certainly. It is the same as drunk driving.
no not really, however driving while your high is a DUI (driving under the influence)
youre driving a ford!
Yes, You can only shift it into 4 high while driving. You can not shift to 4 low while moving.
While driving my cavalier will shift into high gear for at least a couple of minutes. Shifting gears,giving it gas does not help. Any suggestions?

No, not legally. It's Driving Under the Influence/Driving While Intoxicated, the same as if you're driving drunk.
Many things can cause lag while driving at a low RPM but not at a high RPM even if it is not the vacuum hose disconnected from the EGR valve as it could be the fuel filter. It can also be the park plugs.
I would look for a vacuum leak.
