I have a spare map and lambda sensor I took off the car when I had issues before but turned out not to be the issues so could try these again and see. |

I don't know the values I'm afraid but the co was high and the lambda was low the others where fine.

while working on the LPG conversion I removed the oil catch can thing below the intake manifold as this was blocked when I got the car. Upon removing it there was a lot of milky oil drain out and the thing was full again, this had also caused some to go up into the manifold and therefore get burnt which I feel could cause or at least contribute to the problem. What would cause this to block up, it seems its for removing moisture or condensation that collects in the oil. the rest of my oil is fine I have no issue with a head gasket to milky oil on the filler.

so the oil thing hasn't solved it. I changed the lambda sensor because when I did the LPG conversion I wasn't getting a signal from it so put the old one back on which worked and I got a signal from it but the light is still on in the car!? what else could I try?

I think, if i remember right, the light won't go off in this situation without using software to clear the error code and switch the light off. As a desperate measure, you could try disconnecting the battery overnight. (Radio code!)

I disconnected the battery for about 20 mins so maybe that's not enough. I'll plug in my computer and see if they're are any codes on that then.
