I cleaned out my TB and my IAV Valve. Now, whenever I start my car, it idles fine, but if I put it into gear, it timmediately dies. Any advice? I pulled 0401 (air temp sensor) and 0304 (knock sensor), but the car had those before and I never had a real problem. Thanks

is your air temp sensor connected?
0401
Diagnostic Trouble Code 0401 points to a problem with the Intake Air Temperature Sensor. The IATS is mounted in the engine air intake duct, downstream of the air cleaner filter. It detects intake air temperature and transmits a signal to the Engine Control Module. The sensor uses a thermistor, a resistor with a value which is inversely proportional to temperature. The IATS is not directly used to control the engine. It is used only for diagnostic purposes. Therefore the engine should start and run normally, even with the Malfunction Indicator Light on and DTC 0401 stored.
This malfunction is detected when ...
a) An excessively low or high voltage from the sensor is detected by the ECM.
b) The signal from the IATS is inconsistent with the signal received from the Engine Coolant Temperature Sensor.
Possible causes include ...
- Harness or connectors (The sensor circuit is open or shorted.)
- a faulty Intake Air Temperature Sensor
The IATS resistance values should be ...
- at 14 degrees F, 7.0-11.4 Kohms
- at 68 degrees F, 2.1-2.9 Kohms
- at 176 degrees F, 0.27-0.38 Kohms
For further information about the Intake Air Temperature Sensor please refer to the Chilton repair manual (page 4-16) or the Haynes repair manual (page 6-11).

that was taken fronm hte third link in hte sticky for check engine light
maybe if u fix that, it might not die anymore

bad MAF? =P

Take it apart again and put it back together.
I had the same problem once when I cleaned my TB.
Turns out I left one vacuum line off and there was a funky connection on the MAF.
