Possible Electrical Problem?

I Have A 99' Rover And It Is Giving Me Some Lag On The City Streets. Up Hills And Merging Onto The Freeway, It Feels Like It Is Sputtering When I Floor It And The Rpms Jump To Like 4-5,000 And The Mph Goes Really Slow. And Also My Air Ride Susupension's Light Are All On And Wont Turn Off.they Have Been On For One Whole Day, I Followed The Procedure In The Manual To Turn Your Car Off For 2 Min. All Doors Closed And Locked Then Restart, Nothing. It Is Suppose To Reset Itself. Any Ideas?
