havent a clue here to be truthful,it might need a dealer fitter to look at it ,if i had the vehicle in front of me i would sort it out eventually but ??? changing the air flow valve is over 300€ in parts alone ,No i think taking it to the dealers is probally your best bet

When you changed the battery the computer must re-learn the setting again. If it continues have a OBD II reader plugged in and check for codes.

SOURCE: 02 mitsubishi eclipse p507 code.
P0507 - 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.
Potential Symptoms: Most likely you'll notice the idle speed is higher than normal. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.
Causes: 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
Possible Solutions: 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 procedures.

Hi Rodrigo, The idle control is activated by the temperature sender unit. It sounds as though yours is giving a cold signal to the computer and it pushes up the idle speed to compensate as if it has just started. The sender unit is a different unit from that which operates the gauge on the dash instrument panel. Replace it and I believe your problems will be over.Regards John
