Sup, car folks. So I’ve got this P1504 code on my Ford Explorer, and the idle’s been all over the place. It’ll rev up by itself when I’m stopped at a light. Could this be an IAC valve issue? I’m not super familiar with this, but I’m trying to avoid an expensive trip to the mechanic. Any DIY tips to fix this? Thanks in advance!
