Re: Lambda Sensors
i also have the same question, cause i think i have a faulty lambda (strangely only causes me problems in hotter days) and would like to test it.
read some threads that when disconnecting it, the engine run/economy went better, pointing to lambda sensor as the problem.
don’t know if this works for every case, but i’m going to try it when i get the same running problems. also had some months with really poor fuel economy, but not sure if it was before the thermostat change, or the overuse of air conditioning...
