I am having problems accelerating over 3.5k RPMS, Check says I need to replace O2 sensor, but I just replaced sensory 1 almost 6 months ago. At about $300 a pop, I cant afford to keep replacing em. I am wondering if the O2 sensor is the problem w/ acceleration, and if so why is the O2 sensor crapping out on me again? What would be causing it to blow?

Thanks for any help.

 

First off, Welcome to HAN. Enjoy your stay. :goodjob:

How many miles are on your Integra?
And what model year is it?
What specific CEL code are you getting?
How / why did the first O^2 sensor die?

This sort of sounds like it could be a dying catalytic converter...possibly. :dunno:
A bit more info and I can be of better help.

 

Thanks,
64k miles on a rebuilt 98 Integra GS .
The first o2 Sensor was replaced when I bought the car, not sure how it went bad. Not sure what CEL code was. I will look get back w/ u on that one.

 

perhaps check the gap on the plugs. i had this prob once on my 98 gs and i had the gap too big, so i closed it a little and it was fine..

didnt i mention this? one of u mods delete my post?

 

The gap might be the problem but really we're not going to know what's up without the CEL code. To check ECU codes: http://www.c-speedracing.com/faq/06.php
