ok so heres my deal my 98 cherokee i got when i bought it the guy claimed it needed a torque converter well he was wrong it was a cat converter and since then the check engine light has been coming on every couple weeks for cylinders 1 & 2 misfire i changed plugs wires cap rotor all that it quit for a while but then started coming on again the other code it throws is for a mass air flow sensor which i dont have, also my oil pressure gauge is always pegged every once in a while when idling it will drop i replaced the oil pressure sending unit already ive done oil change nothing seems to help but the jeep runs fine and the oils always fine also so not to big of a concern at the moment the main issues are 1. i dont have heat, the thermostat was just replaced the next thing im going to do is flush the heater core. so this issue i think i may have under control. but the other 3 are my main concerns 2.when engaging 4wd every tire rotation it seems there is a clunking noise but it is pretty much only when i turn and i need 4wd i live in ND and the winters get pretty bad also why i need heat. 3. in 2wd when turning i get squeaking noises both issues 2 & 3 seem to be drivers side mainly and then the final issue im stock suspension no lift what so ever and when i go 60+mph i start getting a wobble and if i hit a little bump in the road it feels like my jeep wants to fall apart but its only occasionally not constant any help would be greatfully appreciated
