I was changing my oil and I put it on the ride in Jax and you drive up it and when I was done I rolled down and my suspension in the front was low and it won't go back up how do I fix this and why did it happen

Driving early in am and it is cold(4degrees) . Engine light goes off and car goes into reduced power mode and runs at 30-40 mph. On star says something about fuel injectors. What could this be?

It feel like it's topped out
