Have you checked you oil level? The fuel should have no effect or cause since the cherokee is made for regular fuel.

just had oil changed and i just checked it its fine

It is possible you got a bad tank of gas or because the tank was run low on fuel causing the filter to get clogged and restricting fuel.
