Need diagnostic procedures

[stufe84]

I have a 1994 Mazda B2300. I have a check engine light and had someone pull the error code 224.

I am looking for the diagnostic procedures that tell you what to do in relation to a specific error code. I tried calling Autozone, but they do not carry the book. I also have been unable to find the diagnostic procedures on the internet. Any help would be greatly appreciated.

All that kind of information is in the tech library.

just copy/pasteing this from another thread i answered. hope this helps.



just solved a rough idle/backfire issue myself. Turned out to be a border-line bad coil pack. take a multimeter and test primary resistance from the electrical connector. from either outside terminal to the center terminal should be less than 5 ohms. then test secondary resistance on coil packs between corresponding cylinders (1,4 and 2,3). Should be anywhere from 10k-15k ohms depending on what brand coil packs you're running.

The secondary resistance on one of my packs was 30k ohms and it was bad enough to miss at idle and backfire pretty much whenever it felt like it. But it still ran fine at normal driving rpms.
