Hello, I have a 1992 Crown Vic X-Police Car. I recently replaced the engine with a rebuilt one becuse my sister siezed the engine when I let her borrow it! Now it runs good except for two minor things. Number one only on cool or cold days it will stall out. The past week when it was warm out it did not do it, any clues? Secondly the tranny has been giving me a what feels like it is slipping out of gear. Almost like it's loosing torque. There is no rime or reason to this. It can go a day or two without doing it. Then you can take it for a long trip and it won't do it then all of the sudden it happens. I have no idea what is going on. There is no pattern as afar as speed is concerned. It happens at low, high, and any speed you can imagine. It lasts for a few seconds or if you take your foot off the gas and then reaccelerate it seems to go away most of the time. Kris
