With a bad lamda probe (oxygen sensor) fuel consumption increases noticeable, escape noise can be problems with some spark plug that does not burn due to a former fuel excess to the same problem.
Hello I have a Daewoo Nubira CDX 2.0 of the year 1998 and I have the same ignition problem of the "Check" light and TBN lights the brake. I have to put a scanner, but where I live (Ibiza-Spain) there is no the same plug in my car! And what do I do now to look at that ??? thank you
