This P0507 code is one that's sometimes triggered on vehicles that have electronic throttle control. That is, they don't have a regular throttle cable from the accelerator pedal to the engine. They rely on sensors and electronics to control the throttle. In this case, the P0507 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is greater than the desired (pre-programmed) RPM. In the case of GM vehicles (and possibly others) if the idle speed is over 200 rpm higher than expected, this code will be set. A P0507 DTC trouble code may be caused by one or more of the following: A vacuum leak Leaking air intake after the throttle body EGR valve leaking vacuum A faulty positive crankcase ventilation (PCV) valve Damaged/failed/dirty throttle body Failed EVAP system Failed IAC (idle air controller) or faulty IAC circuit. This DTC is more of an informational code, so if there are any other codes set, diagnose them first. If there are no other codes, inspect the intake air system for air or vacuum leaks and damage. If there are no symptoms other than the DTC itself, just clear the code and see whether it returns. If you have an advanced scan tool that can interact with the car, command the idle higher and lower to see if the engine responds appropriately. Also check the PCV valve to see if it's blocked and needs to be replaced. Check the IAC (idle air controller) if equipped, verify it's operation. If available, try swapping in a new throttle body to see if that fixes the problem. On Nissan Altimas and possibly other vehicles the problem may be fixed by having the dealer perform an idle air relearn procedure, or other relearn procedure

possible causes are:

Dirty throttle body
Electric throttle control actuator incorrectly adjusted/faulty/damaged
Air leak on Intake
Poor electrical connection to the Intake Air Control valve

P0507 KIA Idle Air Control IAC System RPM Higher Than Expected

This P0507 code is one that's sometimes triggered on vehicles that have electronic throttle control. That is, they don't have a regular throttle cable from the accelerator pedal to the engine. They rely on sensors and electronics to control the throttle. In this case, the P0507 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is greater than the desired (pre-programmed) RPM. In the case of GM vehicles (and possibly others) if the idle speed is over 200 rpm higher than expected, this code will be set.

I'm assuming that you have idle high in the engine, and IAC fault code.

DIAGNOSTIC TROUBLE CODE (DTC) 0505 IDLE AIR CONTROL VALVE (IACV) CIRCUIT FAULT

Know Your Circuit:
* In order to regulate the air entering into the engine, the Engine Control Module (ECM) uses an Idle Air Control (IAC) Valve.
* To raise the idle rpm, the ECM handles the pintle inside the IAC valve away from the throttle body seat.
* This enables additional air to bypass through the throttle blade.
* To lower the rpm the ECM controls the pintle towards the throttle body seat.
* This successfully reduces the amount of air bypassing the throttle blade.
* A scan tool will note the IAC valve pintle position.
* The greater the count, the greater air is allowed to bypass the throttle blade.
* This DTC ensures whether a low idle condition exists as defined as 100 rpm below the desired idle rpm.

Pre -requisites For Setting the DTC:
· No intrusive tests are active.
· DTC(s) P0106, P0107, P0108, P0112, P0113, P0117, P0118, P0122, P0123, P0131, P0132, P0133, P1133, P1134, P0171, P1171, P0172, P0201, P0202, P0203, P0204, P0300, P0336, P0337, P0341, P0342, P0351, P0352, P0402, P0404, P1404, P0405, P0406, P0443, and P0502 are not set.
· Engine is running > 60 seconds.
· Barometric Pressure (BARO) is > 72 k Pa (10.4 psi).
· Engine Coolant Temperature (ECT) is > 60°C (140°F).
· Ignition voltage ranges between 11 and 16 volts.
· The Intake Air Temperature (IAT) is > -20°C (-4°F).
· Manifold Absolute Pressure is less than 60 k Pa (8.7 psi).
· IAC valve is fully opened.
· All of the above must be met for more than 5 seconds.




Diagnostic Tools:
* Probe the IAC valve electrical connection for proper mating.
* Examine the wiring harness for damage.
* See whether the throttle stop screw shows signs of distortion.
* Also inspect the throttle linkage for signs of binding or excessive wear and tear.
* The following conditions may be created by a slow or unsteady idle:

1) Fuel system very high or low.
2) Foreign material in the throttle body or in the induction system bore
3) A leaking or restricted intake manifold.
4) Excessive engine overloading. Check for seized pulleys, pumps, or motors on the accessory drive
5) Excess engine oil.

Hope this help.

Trouble Code: P1133 (3.4L V6 VIN E Auto)
HO2S-11 (Bank 1 Sensor 1) Insufficient Switching Print this code data Number of Trips to Set Code: 2
OBD II Monitor Type: CCM Details
Indicators: MIL Details

• O2S1 Details
• MIL Details

Trouble Code Conditions:
DTC P0105-P0108, P0112-P0118, P0122, P0123, P0171, P0201-P0204, P0300-P0304, P0335, P0440-P0446, P0506, P0507, P0601, P0602 and P1441 are not set, engine speed from 1600-2450, ECT sensor over 158ºF, TP angle from 9-18%, Purge command over 36%, Purge Learn Memory over 0.86, fuel level over 10%, and the PCM detected the HO2S signal voltage switched from rich-lean or lean-rich less than 20 times in a 100 ms monitoring period.

Possible Causes:

• Air leaks present in the exhaust manifold or the exhaust pipes
  
• Fuel pressure is too high (i.e., causing a rich air fuel mixture)
  
• HO2S may be contaminated (due to improper fuel or silicone)
  
• HO2S signal high or low reference circuit has high resistance
  
• HO2S heater element has failed, or the heater circuit is open
  
• PCM has failed
  

Your O2 sensor is starting to go bad .recomend replacement before it gets worse

p1133 - o2 sensor, Insufficiant Switching, Bank 1 Sensor 1.
p0131 - o2 sensor circuit, low voltage, bank 1 sensor 1
p0171 - Lean condition, Bank 1
p0300 - Random Misfire

I would be looking at the front passenger side oxygen sensor for issues. It may be bad, it may not be plugged in, bad wiring at harness.

The random misfire may be symptomatic of the o2 sensor problem.

Per your description, it sounds like you have a vacuum leak.
Check all vacuum hoses at the engine, make sure no hoses are disconnected, cracked or damaged.
Disconnect each hose at the source on the engine and see if the engine idle stabilizes.
Let me know what you find and we can go from there.
Regards.
