I am still struggling with my 94 Cherokee. I am beginning to think it may not be getting enough fuel. It is intermittent, sometimes it barely idles and the sometimes idles ok but still seems to lack enough fuel at higher RPM. I have changed the filter and it was BAD (very dirty). How many fuel systems components are there? Pump, Filter, Relay, and Injectors û anything else? How can I test the system? Any ideas and help would be greatly appreciated
