i have a 91 3.0 4x4 and i want to know which wires on the o2 sencer which wires are what ive looked in toyota shop manuals but they dont have a wireing diagram does any one know.

 

there's been enough on the forum here during the last 48 hours to figure that out. are you not looking?

 

HUH?? engrish please

 

leave the man's spelling alone. All of a sudden your the spelling police? If you are so appointed, I suggest going after NORBERT. He got is point across

 

Settle down man, don't get your panties all bunched up....lol... I just couldn't understand what he was asking. I am far from a good speller and my grammer sucks anyway..

 

^fun police

watch out for the freak!



We aren't sure what you are asking. if you could rephrase the question we could help you out!

 

and I will re-iterate my reply:
during the last 48 hours there has been enough interest in the knock sensor to help figure out the original problem, ebonically impaired or not.

 

From the sounds of it he wants to know what wire does what on the o2 sensor.

 

Ragin, 904, lol! He wants to know is wire colors for the hot and ground wires. At least I think thats what he's askin.....

 

Abe...lol... knock sensor... It looks like he was talking about the o2 sensor..

 

I sense that Abe has knock on the brain

 

/me smacks self with wrench

yeah, I guess so.

/me hides.

 

I still like pickles though.
