Ford Expedition-shaking while accelerating and idling.

Once in a while, ususally after it rains. Car shakes when idling and accelerating. It jerks when steping on gas pedal and it doesn't want to speed. Now the "check engine" light blinks before it stays on. I also have air suspension system, will that contribute to the shaking and jerking if I have it on or off.

You need to have the error codes checked. Sounds like it's misfiring.
