Couple of Queries... before purchase!

Well that was a piece of piddle to change over, took me about 15 mins, car immediately running much better almost like a new car!

I had the same - see "Emissions" on the troubleshooting thread. After I fixed mine, I found the fuel economy went from ~26-28mpg average to ~33-35mpg average... and that's mostly fairly enthusiastic B-road driving!! (all part of the limp-home rich fuelling it had been doing)
