P0279 code, rough idle, no power.. ???
Greetings- i am new to the site, and love all the info yall put on here. I have an 04 250. K&n intake, 4" exhaust, and hypertech max energy tuner. Today while stuck in wonderful Dallas traffic, she started idling rough. No cel, just sounded like it was "missing". I was able to limp her home, and when i scanned it, it threw a p0279 code. I reset it, put the stock tune back on, and still no luck. Disconnected the batteries and let it sit for about 5 min, still rough. No smoke, and fires right up. Could this be ficm, or maybe just #7 injector? Thanks guys
