My Odometer has been going crazy! i recently purchased a 1993 grand cherokee laredo straight 6 and the odometer has been going awol it counts 5-6 miles for every mile actually driven! i didnt notice it till a few days after I bought the jeep I verified it by using my GPS. the speedometer works fine so i dont see how the odometer could be counting so fast! i contacted the previous owner and he seemed to not "Not know anything about it " the car drives and runs fine just worried it could really hurt the resale value if i ever wanted to sell it.
