Hi, my 1996 Volvo V40 1.8 petrol has just had the lambda light come on, it comes on after about 5 mins of driving but the car seems absolutely fine!? No reduction in mpg of power etc. Over the weekend I did a bit of welding but had the battery disconnected the whole time, I also disconnected the injectors while the battery was off but put it all back and started fine. Went to fill up with fuel and it came on. I'm in the process of converting it to LPG but all I have done is put the tank in and make some brackets, I haven't touched any of the engine apart from unplug the injectors. I need to sort it before getting the lpg kit on. Please someone shed some light. I did try disconnecting the battery for a while but did not sort it.
