Txred,
On most vehicles, there are three things that go bad that may not set a MIL (code). Those are: the TPS (Throttle Position Sensor), the IAC (Idle Air Control) and Spark plug wires. The first two because the computer can't often tell the difference between a bad sensor and someone doing something that they shouldn't do. The wires only will show as a code if they cause a mis-fire and that can be difficult to detect without load on the engine.
So, inspect the plug wires first. If you need to replace them, hang on, they aren't cheap.
