Please, rephrase the question. You say you have a 1989 Jeep Grand Cherokee, but the Grand Cherokee did not come out till late 92, but was considered a 93 model. If what you really have is a 1989 Cherokee, we need to know the motor size. The rest we can look up and give you the best answer possible.
The Jeep Grand Cherokee did not come out until 1993. It used a 5281090 Mopar filter.

Have your Throttle Position Sensor Checked. Big cause of this. Do you have any check engine light come on?
