hi i have a 90 xj 4.0,AW4 6.5"of lift on 35's and its pretty stock besides having a CAI,exhaust, and extra electric fan and haveing some problems.most important thing is that almost every time i crank the heater on it shuts the engine off well at least at idle haven't attempted when driving and also sometimes when i put into gear it stalls sometimes but i goin to give tune up before worry more about that issue cause doesnt happen alot and its mostly used for offroad does anyone know what the heater issue can be or had this prob before its almost like it kills all power then turn key and heater off for few seconds and its fine thanks
