Oil was changed on truck about 3 weeks ago, 3 days ago truck stated running rough, black smoke coming from exhaust and is using excessive amounts of fuel. so I took it in today had oil and filters changed again and the guy said no clumps, water, gas etc in oil that he changed just that it was very dark...
my check engine light is on for some of my emission control stuff and I had a mechanic look at it last week to give me an estimate on what was wrong he said it was nothing major...just 2 sensors...

Could be an oxygen sensor, coolant temperature sensor, leaky injectors and fuel pressure regulator
