Code 507

[dinok]

Hello guys,

I got Venture 2002 and today start my Check engine lighst to turn on all the time and stays on.
Went to Auto Zone and they give me 507 code, which is high idling or something like that.

What can be and how to clear that check engine lights??
Do I have to take it to the shop to fix that problem or is it DIY job??


Thanks in advance and all help is like always appreciated.

Thanks.
