computer throwing codes p0300- p0304 what could be wrong with this thing? its the 2.0 dohc engine (i know shitty neon engine lol) idles bad and misses randomly on all four cylinders. drives fine and the missing is only noticable when idling. the computer is not indicating the any of the sensors are bad thes are the only codes its displaying. could it be the timing????? engine compartment to interior to exhaust...
Did you find out whst it was? My 97 eclipse does the same thing

a few good things to check or replace would be... spark plugs, ignition coil, plug wires, mass airflow, and the main one... the one I had problems with on my car was the oxygen sensors. I replaced them and now it idles smooth again and never misses.
