The first thing I would do is fix the leaks. All of the hoses and the o-ring can be changed for under $100 so you should do that first. After that I would check the basics, make sure you don't have any vac leaks or other physical issues with your engine and mods.

If after all the basics are checked you could try replacing the sensor on the power steering pump or swapping it with someone else to see if it makes a difference.

Thanks Man! I wasn't sure if I should post that in here but thanks again. I have been monitoring my AP to make sure no codes have come up but nothing has. I was thinking that sensor on the ps pump was going haywire. I am definitely going to change out pretty much everything. Since I can't seem to find just the sensor without getting a new pump. Even rebuild kits don't come with the sensor.

Well I guess I'll be busy. Thanks I appreciate it.
