I have a 2001 Grand Chreokee 4.0Cyl.

Wife ran it alomost out of gas about 2 weeks ago,
since then it been running REALLY bad.

Beening showing codes of p0300,p0303,p0304 and p1285.

Replaced coil pack, plugs,both top side O2 sensors, #3 injector, fuel filter.
Replaced the #3 just today and after driving it about 30 mins, same problem arose with the P0303 code.

At my wits end on what else could be wrong!!!!

PLease give ANY advice that could HELP!!!!
