Junk!
My friend has a 90 XJ, 4.0 aw4. She has been complaining of tranny problems and leaks for some time. It overheated today so I went and helped her out. It's leaking coolant from well I'm not sure but it was dripping off of the serpentine belt underneath the lower big pully among other places. Then there is a line that comes foreward from the bottom, passenger side of the engine that changes to hose as it bends up and towards the drivers side in front then changes back to steel and disappears above the steering knuckle, it was leaking a steady drip of dirty acrid fluid (ATF?) Bubbling out at the connection where it changes from a metal line to hose. and the first big problem I noticed (yeah besides all the dripping) was that as soon as the engine warmed up it began to increase it's idle speed gradually at first but then revving up to freeway sounding speed and kept sounding faster and faster. This explained to me why the tranny has been giving out and must be contributing to her overheating. She explains to me then that it will rev up on her like that unless she uses premium gasoling or a specific fuel clensing additive. Any Ideas at all on what to do first with this "increasing Idle" buisness would be helpful. Thank You.
