EA81 Next Question : O2 sensor


Recommended Posts

Thanks for all the replies

Will I be ok leaving off the O2 sensor,and do i need to plug off or modify anything as a result? Custom exaust planned.

EA81 from 84 GL10.

 

BTW I know where I can get ahold of a complete,supposedly good EA81 turbo FI motor near Lubbock,TX if anyone is interested.

Still in the car and cheap!

 

Thanks,

As for me, I never noticed any difference with or without my O2 on my feedback EA81. Was always about the same 26 - 27 MPG. The ECU did get pissed off after about 10 to 20 min of driving, and turn the light on, but other than that, no real difference that I could see. Now I'm running a weber, with no 02 or ECU.

I have heard that they get "sluggish" after a few years, and it's a good idea to replace them. The ECU can only tell you that the 02 sensor is out of voltage range, it cannot tell you that it isn't repsponding as fast as it used to to changes in the fuel mixture. Also - I like to replace them because they are a real bitch to get out sometimes, and when I get a car that is unknown to me, I replace it, and use a bunch of anti-seize on the threads. And every so often when I have the exhaust down, I like to take them out and refresh the anti-seize on them. But I'm just crazy that way...... had to remove one too many that was frozen beyond belief.
