RUNNING ROUGH

2001 Ford Expedition

Engine Performance problem
2001 Ford Expedition V8 Four Wheel Drive Automatic 80,000 miles

I took my truck off the road for 3 months, It had 1/4 tank of gas in it. So when I put it back on the road and it ran like crap, I thought it was bad gas (water in it). So I drained the gas and added dry gas, Filled it up with 93 octane, But it still is very sluggish and runs rough. With the bad gas in it the check engine light came on. Now the light is still on. It ran perfect when I parked it so what could it be now? It has to be something minor right?

If the check engine light is on, take it to a nationally recognized part store and have them scan the computer to identify the problem. Most will do it for free. Let me know what you find.
