The lambda light comes on to notify you as a buyer that you are getting a bargain.


Its a good point about the cat, if the engine has been running rich for a long time it may have damaged the cat. It would be pointless trying to diagnose the problem until you are sure the cat is ok as a blocked cat damages the o2 sensor or at least causes it to give a dodgy reading leading to a bad air fuel mixture.

I would say the AMM will be ok as the car will barely run if it's faulty.


Once you have established the cat is OK, clean up (replace would be best, to be certain) the 02 sensor reset the ecus and try it again/read the codes with the OBD and see what it says, it might come up with a few things. If there is still a problem with the mixture (EFI) then the lambda light will come back on.


Raid the scrapyard for the parts needed.
