Hi
I am new to this site. I have a 89 cherokee , with 185 thous. miles. It runs well and I have resently replaced the crank sensor for a no start problem I had. I have now noted a flat out miss under a mild load or cruise. It is as if it is just one cylinder. But its so strong it makes the car jump like you hit somthing. Since it is not consistant 3 or 4 miss fires at once , could it be the coil or coil wire. I would like to get ahead of this problem before I end up going
