Well if i owned a 3.0L i would hate my car too LOL! Anytime you buy a car and find a company that usually makes a specific engine for more than 10 years, and has an engine design like the 3.0L (not the supercharged one) for only 4 years, you know there is a problem.
The J pipes are easy to install, just loosen the O2 sensors that are in the center of the cat converter (the front ones are basically kissing the cylinder head) and install the J hooks between the sensor and the cat. Install time: 20 minutes.

Cool... is there enough room to swivel them into place without removing the cat then...?

Strangely, my CEL actually went off all by itself on the way home tonight. It's not done that in weeks...!!!

You don't really have to remove anything to get those sensors out, just take off the top engine cover and maybe the cam sensors from the valve cover to gain access back there and go to town.

I also have a CEL (16815) .. do i have to install two of these of just one?
and any tips on where i can find the sensors on the motor?

any thoughts? anyone?
do i need one or two?

Here is my advice; although I have not yet invested in this repair. From what I've read in the previous posts it appears that the J-Pipes are a solution to the bigger problem. Therefore, as they cost about $30/pipe, buy two for the rear sensors and start with them to see if they cure the problem. The rear sensors are actually easier to get to then the front (pre-catalyst) sensors. Therefore, you may have a more enjoyable and less costly repair by starting with the post sensors.

thanks for the advice :)
just my luck though, the site that sells the j pipes doesnt ship to canada :mad:
gona have to find another place to buy em..

one more question... i recently had my oil changed and they might of overfilled it a little.. would this cause an oxygen sensor to throw a code? since maybe its burning the excess oil off?
i cleared my codes and have driven 200kms already and the code hasnt come back yet...maybe im ok?

j pipes
 

If you get an answer send it my way I have used the Cat cleaner and a couple of cans and it went away for 6+ months but is back replaced all O2 so that not the issue?

thanks
