RPM drop when costing
I have an issue with my 98 xj 4.0 in which I'll be on the highway doing 65 or so and it'll be at a normal RPM with my foot on the gas around 2800 or so. But if I let my foot off the gas, the RPM will drop to about 950-1000 and then go to about 1200. It seems very strange. Is this normal? What should I start checking if it isn't?
Thanks in advance.
Thanks in advance.

The same. I don’t think it’s normal.
