My Cherokee has 150K, sometimes I need to jiggle the shift lever (3spd Automatic) just right to get it to crank. Do you think it's the neutral safety switch or a linkage adjustment? Anyone else ever experience the same problem? The problems tends to be worse when I do quick trips. Moe ( my cherokee's name) has been over the river and through the woods and around the block a few times. His still strong and I want to keep him Jeeping.
