P0505 means the whole Idle Control system, not only the IAM. Check all related sensors (i.e. crankshaft sensor). Check with a voltmeter direct at the connector of the IAM if you get any signal. Remove the IAM from the TB, connect him, let someone switch your ignition key to ON. The IAM need to drive in/out for a short time to find the right position. Hold the IAM near a hard part, that they cant drive out completely! If IAM works fine, check the fuel pressure, check and clean your TB ( if not done yet). If that doesn't work, come back again please

Hello...

P0320 means "No Crank Reference Signal To PCM"

The Crank Position Sensor needs to be checked.

P0301 is #1 cylinder misfire detected and is most likely related to a worn spark plug that is need of replacement. All plugs should be replaced if replacing one. Not sure how many miles you have on this vehicle, or if plugs were ever installed, but this is the basic step to take in diagnosis.

p0320 is-- ignition/dist, engine speed input curcuit malfunction. Check the two hoses on either side of the engine that go to the intake. Any kinks or cracks will give crank error. I beleive you have a bad crank sensor. not sending signal to pcm. crank sensor symtoms-- No RPM Signal to PCM . also check wires to crank sensor.
