Throttle Position Sensor (TPS).
When mine went bad, the Jeep was revving its tattas off in Neutral.
If yours isn't revving high (1200 - 1500 RPM) it may be OK and the code just needs to be cleared.
A simple reset may do the trick but may cause your Jeep to run rough briefly again.
To reset, you can just leave your spotlights on again
Use the more civilized method...
1. Disconnect Positive battery lead terminal and touch it to ground for 30 seconds (Once the lead is disconnected, I attach a jumper lead and touch it the Negative on the battery
2. Reconnect the Positive battery cable
3. Turn ignition switch on (DO NOT crank or start the engine).
4. Turn headlights on
5. Turn headlights off
6. Turn ignition key off.
This will reset the engines computer and clear any stored codes (except 12, because you just disconnected the battery)
Jeep may run rough for a minute or two until it relearns itself but will soon smooth itself out.
