ah sounds good chaps, cheers
not sure about removing the air filter though, cos if i have more oxygen going through then even if it lowers CO, won't that raise my lambda? I need that to go down.. do you think it's been caused by an air leak somewhere?
i will defo get some new plugs in, also will get a multimeter to check the coolant temp sender, although i replaced that about 10k miles ago :S
if the thermostat was broken, would that make the car carry on running rich? or is the ecu only told the heat of the engine by the temp sender?
finally, i think that stuff is redex.. i will give it a go, it clears out the injectors or something don't it? how much of it do you need to use for it to take effect?
redex is one such item, however this was something stronger - I think it was by millers but i cant be sure as it was a couple years back now
