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
I Feel Like Dying
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?
Hemorrhoids
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.
