Got some today to look at the Volvo. Cleaned the plugs, removed the metal air pipe from the bottom of the air box, stuck in a bottle of the cataclean, and let the car run for about 45mins.
Prior to that I realigned the exhaust, tightened the clamps and sealed the gaps with some putty. According to the previous owner the cat had been stolen, so it looks like a generic system was fitted and not very well. Stuck on new exhaust rubbers as well.
A little lumpy at start up but after a while she was ticking over nicely, no more soot out of the exhaust as well.
As requested I checked the O2 sensor ( I think correctly) and the reading on the multimeter was about .5, with a little fluctuations either side.
