Hi. I have the same thing. The code I pulled TODAY is 1405.
It is a censor on the top/back of the engine. It says upstream hose clogged or off. I am posting to ask, do I have to remove my air flow system to follow the hoses. And does anybody know which one is the upstream?
I also have a 96Gl ATX
And was informed that the Tranny is NOT going to die on you. So don't get nervious thinking your tranny has to bee replaced.
That only goes for the 1405 code. The others I have no F'ing clue.
