I got the code initially at the tail end of a track day, I cleared it and had no more issues for the rest of the day. It has since come back 3 times now, all under normal driving conditions and each time I’m getting more and more symptoms. At first when I’d come to a stop, the idle would drop to about 600 rpms and then come back to 750. Then it was that in addition to a strong fuel smell, and now when I come to a stop the idle will drop to 500 come up to about 1200 back to 750 but stumble as if about to die but it doesn’t along with the fuel smell. I’ve read about the high pressure fuel sensor and cleaning the air flow sensor, but does anyone else have insight as to what could be causing this. I have full bolt ons and a 91 tune. Thanks.
