oxygen sensor

[ab56452001]

hi, i am going to install a new oxy sensor, i have read somewhere that after instalation car must be started and held at 3000rpm for computer to reset !, is this true or b/s?, thanks.........

Restart the ECU first just pull both leads off the battery for 1-2min or in the time your doing the Oxygen sensor would be best. Then start it up, I'm not sure about the 3000rpm thing.

It says to i the manual i've got. I do it if i disconect the battery, but its a good idea to warm the car up first then disconnect the battery and reconeck it then hold it at 3000rpm for 10 secs

it doens't matter a whole lot. the ECU will remap itself over time, you won't do any damage either way.

when you put the new o2 sensor in run the car for a bit until the manifold is warm!!
it supposedly makes it easier to get off

Or just stick a can off wd40 on it that also works

I'm thinking when i do myn I'm going to have trouble getting down there, I'm a big guy i have stuck my body in places man wouldn't but i think my shoulders are a touch to wide to get a good grip in there, Is it changeable underneath at all??

i dont think you could get to it from underneath!!
it is a bit of a mongrel cause you cant get a socket over it cause of the wire

So just stretch and wrench it off Take off the air intake hose to.

For the 3000 rpm thing.. When you reset the computer, holding 3 grand for 10 seconds helps reset the idle air control valve. Usually if you don't do this the car will idle real rough and pour smoke but will probably reset itself next time you drive it anyway.
