really should put the right lambda in, not sure what you've looked at, but your original fault may not have been the lambda, did you check/change air filter and sparks first, how's the rotor arm dizzy cap look? are there any leaks in the pipes from the air filter to the inlet manifold? after these disconnect the battery for 10mins and the lambda light should go out if it trips again then it time to look at the lambda, hope that helps
