Why does it have a skip, most prevalent at highway speeds?


You aren't saying what the manufacturer of the vehicle is, no the year, make, model, or engine size. However, if you are a commuter and drive long distances daily at a fairly constant speed, over time what can happen is that the Throttle Position Sensor (TPS), can get a "dead spot" in it, where there will be a dropout of the signal to the ECM and an accompanying hiccup of the engine. It feels like a misfire, but only happens occasionally, and only at certain speeds/rpms. It will usually get worse over time. As a test, try driving one trip about 5 mph slower than usual. If you don't get the issue, change the TPS and see what happens.

Engine sputters and hiccups when driving


Sounds like you have a cylinder misfire. Is check engine light on ?, Have you had the vehicle somewhere to get a code scan? My assumption is that you have an ignition problem that is causing the rough idle and jerk feeling while driving.
Take the vehicle to a shop and have them diagnose the driveability problem that you are having.

Throttle stuck on 1996 concorde just suddenly excellarated (800 rpms)


This car has computer controlled automatic idle speed control, the throttle cable is not likely the problem. Have the dealer run a special test to ID problems with this idle speed control system called an "Key on engine running fault code test"

Reduced engine power light


The ECM is stalling the throttle control to limit the RPM , there is a code failure that must be checked to find wherein if you have skipped a maintenance or if there is a faulty sensor.
Too much of electronics has made it hard to users , to depend on the service support of the dealers even if you skipped your schedule.
Take a code check to confirm.

U need to have the cars computer scanned for stored codes, which will give u an idea of what to do.
Most parts stores offer free scans, they just plug into a port under the dashboard, and can have the codes in a couple of minutes, will explain what they mean, and what u should do. If u have any questions after that, u can post another request here.
