check this out, put one on my 05 grand prix when i took the cat off, worked like a charm...

$50????????? You can do the nonfouler trick for 1/5 the price.

 

I noticed it asked "Add to Cart" about 5 times before it listed price!

And it is about 10x the price. $4.99 at AZ.

 

this works?

 

The 8 bucks it cost me to fix mine with a non fouler seems the better route

 

Just scroll down, it says $49.99 towards the bottom.

I agree, a package of two non-foulers is way cheaper.

 

My sure fire way to correct the issue is proper maintenance (replacing the O2 sensors at required intervals; ensuring the plenum is intact; air filter changes per the maintenance schedule; and running a catalytic converter.
