Ok guys I need help here I have a 98xj classic it will is and idle fine but when you put in gear and try to drive it falls on it’s face and starts to back fire and makes no power I’ve replaced tps , maf basiscly all sensors except the crank sensor the codes comming up are for high voltage to one and the other is for 2nd o2 sensor . When replaced and cleared same things happening I’m going to change the. Coil next just did all plugs and wires also .please let me know if you have any remedy to trouble shoot here
