just bought a used 1996 Subaru legacy outback awd postal vehicle. needless to say I didn't get what I paid for. first issue after running on mail route for 3-4 hours, car starts surging and jumping like breaking and horse in. first several hours runs great. tried fuel addatives, high grade gas, no effect. then will drive for a few days and no problems, then it starts over again. any suggestions please. my neck and back are suffering from whiplash. one person said fuel pump. but it takes 3-4 hours before it starts acting up. I would think fuel pump would be more consisted acting up.
now next problem was sold AWD, no fuse in firewall fuse link but yet no AWD. was told clutch pack. never heard such a thing possible help with diagnosis and maybe part number to let mechanic, which I may be 75% considered a mechanic but a real mechanice to repair.
any help greatly appreciated. would like to deliver mail in a car and not on a horse, but true with the horse I would at least have afd(all foot drive)
