Doug,

Thanks I talked to the last guy who did a lot of work on the car and cleared the OBD readings due to the advice that if it was a real issue the light would come back on. As you say because of the coils how could it be on side. Anyway the car runs fine and no sine of the light coming back yet. If you look at the earlier post one of the
MIL ON, Misfire (see above!) Fuel,Comp,Catalyst,Evap,Sec Air,O2 Snsr and last but by no means lest O2 Htr.
You can see that it did call out the O2 Sensor. How hard/expensive is it to replace these?

Thanks James
