Hi,

I've recently started experiencing loss of power on my 98 H22A lude with approximately 110k miles on it. It seems that the loss is only noticable at WOT, 'casue at partial throttle it pulls quite well. I've also noticed that my gas milage has gone worse by around 10% and it seems to run too rich, as I hear much more backfiring now than before.
So what do you guys think, has my o2 sensor gone bad or is it something else?

Thanks.

 

Forgot to mention that its a European model, so its OBD1 and has only 1 o2 sensor.

 

test your o2 sensor to find out. Check the voltage.

 

What's it going to hurt to get a new O2 sensor?? A Bosch universal is like $50...

Yea, I also thought the same, but still wanted to check if o2 senser at all can cause such problem.
