After cleaning Throttle Control Body (did not open butterfly with my hands - used the accelerator pedal to open it and then clean it - I used Throttle Body cleaner spray for it) started getting this code. Got annoyed, and did it again, this time taking it out and cleaning it - also disconnected the MAP sensor from it and cleaned it with Electronic cleaner spray; also took EGR out and cleaned - cleaned MAF sensor to, using MAF sensor cleaner spray. To make it better, not just the P0507 shows up, but now I am getting a P1129 - tried to do the "Idle relearn", several times, but did not seems to work - cleared the code with the scanner and also disconnecting the battery - I will change oil next week since those several tries of relearn running the RPM 3K for "x" amount of tine, probably burned the oil - I will change it before trying again - I was forgetting, all started with the car trying to overheat, and i found out that the radiator had some damage bellow so, I changed it. I did the purge 2 times, and still kind of trying to overheat - just found out that i have some problem with the small reservoir since i listened it making some sound of air escaping/leaking from it - So, any help for my adventures?

So, I have included the correct way to set the idle speed so we can be on the same page

P0507 - Idle Control System RPM Higher Than Expected:

This indicates there is a vacuum leak around the sensor, can you double check the O ring seal that help mounts the sensor?

P1129 - MAP (Manifold Absolute Pressure) Sensor Higher Than Expected:

Check out the images (below). Please upload pictures or videos in your response of any problems so we can see what to help you with.

Thank you Ken L, I had some doubts about that O ring.; I remember now that, when I put it together, i had some difficult putting (inserting) the MAP sensor back in its place - I will let you know by Monday, after I also find another O ring to replace it (should have done it from the start).
Thank you again, I will let you know by Monday.

Sorry, i was forgetting; as per the P0507 - Idle Control System problem, I will also let you know later, after I replace the Oil - I have tried it so many times without success, that my oil seems kind of burned (not counting that I just went to a 3 1/2hs straight drive Wed and again Fri. Maybe the P1129 (MAP) had some influence with the P0507 not allowing the relearn - I will let you know.
Thanks again

Yes, if the vacuum is leaking it can affect the engine idle and cause the P0507 code. Have a good weekend :)
