Question about Daihatsu Cars & Trucks
The engine has been chugging lately and the battery died on me on a wet day, bumped the car and it hasn't failed to start since but does sound terrible though i put that down to the exhaust needing replacing?

The P0420 code, usually associated with a weak cat converter, is in fact often caused by an ageing (weak) downstream O2 sensor. On both my cars at around 150K miles replacing the downstream O2 sensor was all that was needed to clear the code. No cat replacement was necessary. If one actually spends some time reading the diagnostics procedure for this code, they will find that the O2 sensor diagnostic is the first thing to do before replacing the cat converter. The downstream sensor, the one after the cat converter, gets "lazy" with age. This means that it no longer produces voltage signals as it used to. The result is that the voltage swings that come out of it begins to follow very closely the voltage that is generated by the upstream O2 sensor. When this happens, the car computer thinks the cat converter does not do its job (which might as well be the case too, but the O2 sensor is the first thing to try). With a code scanner with live data stream you can see the voltages coming from the O2 sensors.

- I got some details there. And see my comment for Dennis above here too
