stalling after starting

Got new exhaust fitted on monday. Rangey hadnt moved for 4 weeks. Went out earlier, started fine, then stalled. Did it again at traffic lights, then in B&Q. It did it a couple times before, but didnt realy think much about it as was only when 1st started up. Im thinking dirty idle control valve or gummed up throttle butterfly? It a 95 v8 p38

Also noticed that when changed the lambda sensors fron one set cats to the new one has chafed on something and has rubbed through the sleve and insulation on one of the wires.

when was the last time you changed your spark plugs, look at them befor you start stripping anything else..
