WOW!!!
I never expected my new oxygen sensor to do this much difference!!!
- no more puff of smoke when i start the car
- runs nice and smooooth
- no more stong smell of gas
- idles steady @ 900rom(i know its supossed to be lower 100rpm but this is not a big deal) not waving between 1200rpm and 900rpm

I guesse almost 400 000 kms on the clock(dunno what it is in miles) did it for the o2 sensor.( the cars still on its original engine ROTARIES CAN BE RELIABLE!!!)

i extremly recomend this for any GSL-SE with higher mileage its worth the 29.99 trust me.

 

I second the motion! I just changed mine on Saturday... Not as drastic of a change as GSL-SE got, but very nice... The fuel smell is certainly less, and the throttle response seems much quicker than before. It doesn't have that have backfire gurgle on decelereation either (of course I kinda liked that sound ) A must before trying to solve other issues. Just ask POSracer... The K.I.S.S. method works wonders...

 

Yep, O2 sensor made a big difference on the POS Racer! My improvements are more in line with rx7gslse, noted improvements. Plus it was an easy job! Love them easy jobs that give you big results!

 

Where did you pick up your O2 sensor from. I might put one in as a reliablilty modification.

 

I got mine local at AutoZone it was a Bosch sensor.

 

I got mine from victoria British along with another order, but it came w/ a female connector rather than a male which I needed so it required a trip to radio shack to remedy... No reason to do that... Don't recall price off the top of my head

 

Bravo!

Amazing that one little part (not broken) can make such a difference. I'm thinking of swapping them out on all of my fuel injected cars.

I got mine at Kragen, the Bosch.

Don't buy Mazda, +$100 more than the OEM aftermarket.

 

same here but instead off going to radioshack i used the old male connector for a sure fit

 

It was 29.99us from victoria british and it took a hell of a long to get here

 

If your running no air pump like I am, you'll notice an good difference with a heated O2 sensor too! Less time to start working in the morning.
