Fluid leak and occasional fluctuating idle

[mechman3]

I have left my truck parked a couple of times for about 4-5 days. It starts right up but on both occasions under the drivers side toward the firewall I have a fluid leak. My driveway has a good incline to it and the leak is enough to flow downhill about 3 feet or so. It feels greasy but somewhat "dirty" clear. I also seem to have an occasional fluctuating idle but not enough to see on the tach just a slight uneven sound to the "normal" idle.

Any suggestions would be as always very much appreciated.

Sound maybe normal.

Check your hydroboost for a leak where it meets the master cylinder

Have you smelled the Fluid? There are 2 fuel lines that are in the area that transition from steel to rubber somewhere in that area. Also as mentioned the Power steering lines are known to leak at the hydro boost. You should also check the oil cooler to see if the coolant is leaking from the steel water pipe that comes from the water pump. Coolant on the ground will keep a "wet" puddle about that size.
