Power steering fluid drained out onto garage floor in huge puddle. Receptical was empty. Mechanic says hose is old but power steering rack is cracked. $500 for part, $700 labor. But says he can quick fix to last a couple of months. What would cause this and why so expensive to replace.
The parts that need to be replaced is the whole power steering component that actually turn the wheels.Don't let him temp repair it...that's a waste of money. Make sure there is a wheel alignment done after the parts are replaced

I'm wondering if your injectors are leaking. If they are, and the car sits for a period of time like you're saying, fuel would puddle up and the car would run extremely rich until the excess puddled fuel burned off. Did you (or do you) notice black smoke from the tailpipe during the time the car is running really rough? Take a look and see - rev the engine if you need to, and see if you see some. It'd take a few minutes to burn off, and once it did, as long as the rest of the car is working right, you'd run normally. If you shut the car off for a short time (ie, getting gas, renting a movie) the car likely wouldn't sit long enough for enough fuel to puddle up for the condition to recur. If you park it overnight, that's plenty of time for the injectors to leak enough fuel for the car to run rough on startup.
No guarantee of course, but that's what sounds like a worthwhile investigation to me.

Three areas of concern. A leaking steering rack: By looking under the car, look for the rods which tie the left and right wheels together in the center. By turning the steering wheel fully to the left or right, you can look behind the front wheels 1/2 way down and you will see the rod I am referring to. Following the rod to it source of attachment, it will have a rubber bellows type cover surrounding is as it gets near the center of the car. If the rubber is torn and has oily residue, that is where you are loosing your power steering fluid. It is a leaking power steering rack. A fairly expensive repair, best left to a professional. Buying a used one is a real crapshoot because they are very prone to failure as they get older.
2. The high pressure hoses will leak on these cars. It is difficult to see these without putting the car on a lift because the pump is on the firewall side of the engine. If you notice the fluid dripping near the pump, it is a higher probability than not that it is the high pressure hose than the pump. Also look at the return hose coming from the reservoir, Sometimes the clamps aren't that tight and it will cause a leak, but your description sounds like a leak under pressure.

Hard to say. It could be a loose hose clamp if it's a slow leak.
