Sorry if I sound dumb but I'm new to this forum. Being a previous YJ owner and now an XJ owner I'm lost as to what the issue is with my XJ. I just bought this XJ on Sat night. The fella I bought it from told me that occasionally it would die when put into drive and would be hard to start afterwords. And he was correct. So being a descent shed tree mechanic I bought it anyway. I have replaced throttle position, crank position, can position sensors, checked that all grounds were tight and clean, checked connections at battery. Any info given as to what my next direction to head would be muchly appreciated. Also need some info as to hooking up a.c. lines. Since the compressor is located in a different area. Has new condenser, compressor, evap, and new lines but they aren't the correct ones. At least I don't think they are. Thanks in advance for info.
