So on my 2000 Cherokee 4.0L I'm having misfire issues with a CEL code P0205. When I idle the CEL stays solid. When I drive it blinks misfire and I can't go over 3000 rpms. BUT!!!! When I'm on my last gallon of gas it runs fine, rev all I want, solid CEL.. I still get the code though. Wtf. Test lighted the injector wires all good, put in (old) new injectors... Going to try some ford 19lb injectors tomorrow.. What's with the tank though.
