Okay I have been having throttle body issues for weeks now. My throttle body won't save for some reason after its been "set" and getting P0507. It first happened when I got i t cleaned. It didn't want to save after so I just bought a new one from amazon (hitachi). Installed and tried resetting with computer. And then pedal. It would go but then turn the car off and it's gone. Thought it was defechive So I returned it and bought a hitachi from autozone. Slapped it on and got the same results. It didn't want to save. Thought it was the brand (even though hitachi is suppose to be the oem brand) so I bought the cardone remanafacture from autozone. Did the pedal reset and still having the same results. It won't save after its been set. No idea what to do.
Just wondering if there is any reason why it wouldn't set. Any at all. Just need a clue or something. I know theresome like a million of these threads but none really addresses my problem.

I had the NTB 75mm on my Maxima and had the same issue but the computer relearned it after driving it around. Try to drive it for 25-50 miles after the pedal dance or try to reset the car by leaving the battery unplugged overnight.

It has to be asked...
You didn't open the butterfly valve manually did you?

 

What do you mean by "save"? What's the car doing that has you thinking there's a problem? Is it idling high, hunting for idle, stuttering, etc?

There's several procedures that need to be done after cleaning/replacement:
ECU reset
Throttle body closed position relearn
Idle air volume relearn

I'm sure you've found instructions for all of those. The only thing I can add to the IAV procedure is to make sure everything is fully warmed up, go drive around for 15-20 minutes, THEN perform that procedure.

 

I will try the battery trick. But is that before or after the pedal dance. I also drove the car a good amount of miles after I did the dance. Turned it off and same results

 

Po507 high idle. And what I mean by save is that. I do the pedal reset and it works. Idle goes down and it's all good. Turn the car offor now and then turn it back on its back at it again with the high idle. It won't save or stay at the low idle

 

Try revving it a few times, turn it off and then on immediately afterwards.

 

What is revving suppose to do

 

It's part of the procedure.

 

If your talking about revving it after 20seconds that the car been started (after the pedal dance) then yes I have done that

 

Fixed the problem. Apparently unplugging the battery over night seems to have done the trick. After leaving it plugged out. Did the pedal dance. Drove a little. Aggressive and easy. And restarted the car and it went good. Who would of thought just plugging it out would fix it.
