upstream o2 sensor
Sorry if this has been asked before, because I'm sure it is. But I cannot search the forums using my cellhpone. Guess that isn't a feature?
Anywho, I am trying to replace the upstream o2 sensor on the drivers side. It's right on the exhaust manifold and can't seem to get a wrench to it. Am I missing something or am I supposed to take of the manifold to swap own sensors?
