182 eats lambda's

[bozothenutter]

Hi,

I will soon be on my 4th lambda in about 6 years......
anybody else have this problem?

car is RS2'd and mapped by Fastchip, it runs very normal with a new sensor (no errors etc)
I have tried expensive and cheap Lambda's, no difference....

anything I should check?

Get it properly mapped?

Went through 3 genuine lambda sensors on cup with rs2 fitted.

so it's just a RS2 thing then......
not suspecting the map, as Henk has got a good rep on the dutch forums.

any idea what would be the cause of them to fail?

how are they failing, what are they doing or not? how are you confirming failure?

Without trying to hijack this thread, what's the best way to diagnose a failing lambda? My mpg is seriously bad at the minute, any other ways of checking if it's the lambda other than swapping them around?

look at live data/scope it and check it's switching as it should do.

last one was no voltage when warm, others were heater circuit and not switching between the correct voltages
Usually when cold idle is bad en mpg is low I know something's up....read from OBD usually shows the pre cat lambda

does your temp gauge go up quickly and to the operating temp? mine didn't and was about 10mpg down, transpired there was a hole in the rubber seal on my thermostat, changed that and bang sorted
