Look at the very first sticky thread on the Problem Dianosis page. The OBDII key for our cars is there.

P1507 Idle Control System Malfunction (Fail Safe)

Sounds like your car is in safemode. Reset your ECU by disconnecting the battery and draining any remaning charge by pushing on the brakes. See if that fixes it. My question would be what did you do to cause it to go into safemode.

Check all engine grounds from the battery. Make sure you have no loose grounds. This CAN cause abnormal idling and thrown codes.

sounds like an IAC issue (Idle air control). This allows air to pass when the throttle butterfly is closed to maintain idling conditions. It sits atop the TB. Check your throttle cables to make sure they are moving freely and not getting caught when returning to idle position, if they are fine, you can remove and clean the IAC with TB cleaner, but that's probably just a short term fix, probably need a new one.

At least clean and see if the problem goes away, then you'll know that's the prob.
