I have a 05 6.0 with 104k on it that I haven't driven in probably 3 months due to another truck purchase. It starts and idles great, even being 0 degrees f here right now. Sitting in park if I run it up to 1500 rpm it runs rough and smells like raw fuel, and smokes slightly. Driving it down my short road it just blows smoke and barely runs but then when parked it will idle fine.
On my scangauge II it shows p2262 but no CEL. The map sensor hoses and fittings are clear, I was wondering if it could be a plugged cat, or what else to look for? I will download the rest of the xgauges on my SGII tomorrow, but wondering what else to look for? Sorry for long post but i couldn't find anything similar, mostly no starts which is opposite my problem.
P.S. Truck is bone stock except for cat back exhaust, and i have cleaned egr reguraly at 5k to 7k miles
Thanks Jesse
