Question Answered: 

Check weather strip around the passenger door for cracks or cuts. Also on the passenger side under the glovev box look for any cracks on the plastic casing. check to see if there are any water leaks there. you may need to remove the kick panel to have a better view. I have seen cracks there before causing water leaks.

Is it automatic or manual? Slipping automatic transmission will feel like your car is going in neutral during acceleration thus increasing the rpm and a non shifting auto transmission will have your rpm really high but not pick up speed.

First check tire condition. Is the threads even, is it worn? Also have your wheels balanced. Second check your steering and suspension components for looseness or worn bearings.

Question Answered: 

Have your oil pressure checked. you may have a bad oil pump. There is a bulletin for oil light flickering if my memory serves me right, but that is just for a bad connection to the oil pressure sensor and not cause any knocking noise.

Question Answered: 

You will need a wiring diagram to see how this is hooked up. Have a technician diagnose it for you. Most likely you have a power line shorted directly to your pump bypassing relays and air suspension fuse. Or you may have a leak in your air suspension lines and air strut continuously running your pump.
