Recently had someone clean throttle body and codes p507 &p327. Noticed butterfly flap doesn't shut all the way when taken apart. Can that part be replaced, is that normal, our does the while throttle body need replacing. Had relearn done at shop with some machine and it didn't work. Can butterfly be adjusted or just that part replaced? Thanks

 

Not sure if this will help your problem, but it's worth a try before you spend more $$$.
After warming up the engine turn it and all accessories off and perform the following procedures in order:
ECU Reset
Accelerator Pedal Release Position Learning
Throttle Valve Closed Position Learning
Idle Air Volume Learning (Throttle Position Learning)
If your idle is still high after an engine restart, try the following:
ECU Reset
Accelerator Pedal Release Position Learning
Throttle Valve Closed Position Learning
Idle Air Volume Learning (Throttle Position Learning)
Let the idle get down to a stable 650
Unplug the MAF sensor, the engine should die within 5 seconds.
Reconnect the MAF sensor
ECU Reset
Accelerator Pedal Release Position Learning
Throttle Valve Closed Position Learning
Idle Air Volume Learning (Throttle Position Learning)
Seems like a lot, but it worked for me.
