Have the fuel trims been checked? These (short term fuel trim - STFT and long term fuel trim - LTFT) can be checked with an OBDII tool, and can provide a lot of information about what may be happening. If you have a vacuum leak, for instance, the O2 sensors will report a lean condition to the ECM and it will add fuel to the engine to try to correct. You will see this in the fuel trim numbers.

So, yes, the ECM can cause the misfire, BUT if so, it's because something is not right in the engine. Have a qualified technician evaluate ALL parameters and determine what may be wrong. You've spent a lot of money on parts (O2 sensors, coils, plugs, wires, PCV valve and hose, alternator), and have invested a lot of your time. It's very possible that none, or only a couple, of those parts needed to be replaced. Invest in the expertise of a trained technician.

i know on some factory radios the radio code is sometimes on the back of the radio or in the owners manual. if its not there you will probably have to call the dealership and get it.

INSTALLING NEW BATTERY.WHEN DISCONNECTING BATTERY CABLES THE ECM WILL LOSE IDLE CONTROL MEMORY.TAKE TO MAZDA DEALERSHIP LET THEM RESET ECM SO CAR WILL IDLE STOP STALLING AT STOPS.

The ECM seldom goes on any vehicle.There is two things I would check.One is fuel reaching the injectors?.Check this first.Two are you getting a spark?

yes the blub is blown you have to remove the radio to replace the bulb give these websites a try www.alldatadiy.com and www.autozone.com if all fails stop by your local Mazda dealership in the parts department and they be able sell you the bulb and give you the pictures and diagrams you will need wish you the best of luck Michigan Man.

check ebay. otherwise, it's a call to the parts department at your local mazda dealership away.

if u call the mazda dealership they can email u a diagram with the part numbers on it.
