    lambda confusion

    right i took my old lambda off due to the car getting jumpy and put on the spare i had, the lumpyness has now gone but the eml light is on

    what confuses me is that when the old one was in the eml never came on, but with the new one in it comes on within seconds and doesnt go away. tried leaving the battery off but still stays. any ideas?

    Erm I dont know if this helps or not but I had mine knocked off by a speed bump a little while ago, so when i plugged it back in the eml was still on, I tried resetting the ECU many a time but the light went off by its own accord a couple of days later :-)

    read the code to see exactly if it relates to the new lambda or an associated fueling issue. by the way have you replaced correctly (not glued) the fuel pipe your mate busted because if not then you will be chasing fueling and lambda issues for ever and a day mate.

    na fuel line issue has been sorted properly by a qualified machanic, the code that shows up is for the lambda but it showed up before which is the reason i changed it lol. i dont feel confident disconnecting the ecu to reset the code as ive never done it before, just dont understand why the light comes on when the new ones in, put the old one back on to see what happened and the light went off but it became lumpy again

    this should tell you then that both lamdas are not in range, one brings on the light and one makes the car lumpy. try a new one form http://www.lambdapower.co.uk they offer genuine Bosch units at a good price. why not then disconnect the battery for an hour to clear the ECU memory and then connect back up and take car for 30 minute drive and see if the light comes back on
