TRUCK IS MISFIRING/TREMBLING

2003 Ford Escape

Engine Performance problem
2003 Ford Escape 6 cyl Four Wheel Drive Automatic 125000 miles

I was driving home through a nasty rain storm and drove across a flooded street. The water didn't pass the tires so I pressed through the water. After I made it through my truck began trembling when idling and sort of feels real heavy. What's the damage?

Engine running rough or misfiring can be cause by the following: 1. Defective spark plug
2. Inadequate spark/coil, defective spark plug wire.
3. Lack of compression
4. False air leakage.
5. Faulty fuel injectors.
6. Insufficient fuel pressure.
7. Contaminated fuel.
8. EGR valve that is leaking.
9. Oxygen sensors.
10. Throttle position sensor.
11. Idle air control valve.
