The good news is that testing a misfire code, or misfire codes, or a rough idle condition is not that hard and it's something you can do! In this tutorial, I'm going to explain in some detail the most common causes of misfires and misfire codes (P0300, P0301, P0302, P0303, P0304 -OBD II equipped 1.8L Toyota).
Solder flux is a type of metallurgy component used when soldering two metals together. The flux is an inert substance that prevents the formation of metal oxides at extreme temperatures.
Without flux, the solder will simply sit and can be scraped off the surface. Flux allows the solder to bond with the surface. It cleans the oxide before soldering. To have a good solder bond, oxide must be removed, for this flux is used, this allows a âwetting actionâ to take place.
