ok it seems everytime my 93 xj goes into over drive (45-55 mph) it has a slight miss to it. i dont know what the problem is with it. it has freash fluid in it. doesnt slip at all in any gear. just that shudder once in a while. ive searched all over internet and all ive found is ford trucks with this same problem and the fix was change coil packs. if any of you had this problem please let me know how you fixed it.
