Lamda sensor testing help please?
I got a suspicion about the lamda sensor. I have problems with some automatic system that regulates on the carb. the electronic nozzle. When I drive, the car drives slower in regular intervals. Then it seems like the car gets to little fuel, and then suddenly works well for a few seconds. About 5 sec good, and then about 2 sec poor. Mostly the fault operates around 2000 rpm. It could be a broblem with a leaking tube, I know. But I dont know all the important tubes to look for.
How would a properly working car behave when the lamda sensor is disconnected and you take a drive? Should this problem be the same or is there any other way it works?

Are You from Baltic states?
I believe Lambda sensor is called O2 sensor here.
It would help if you mentioned year and model of car.Driving without lambda sensor would probably cause rough idle and check engine light if applicable.

Re: Are You from Baltic states?
Im from Norway. Do I write so bad?
Now I tested it again, with the sensor disconnected in a different way. I connected the two lead wire, and disconnected the one lead wire. This is because the one lead wire goes to the actual sensor. Then the point is that after this operation the car runs much better. No stuttering, and I suspect that the mixture is much more rich, and the engine instantly responds to my will. The two lead wire is probably a preheater, and the one lead is the one actual sensor wire?
