service engine light on with hfc?

[evolutioner]

So my service engine soon light came on today. My friend ran a scan on it and it is my O2 sensor. I have a high flow cat why would I be getting this issue? I went with a cat and not a test pipe so I wouldn't have to deal with this problem. What do you think that I should do?

Well, if the hfc is giving you this problem, then you should probably pick up a tp and an anti-fouler plug for your O2 sensor. Then have your friend erase the code, and have your tuner retune your EVO for the tp.

Here's the website for the anti-fouler plug: http://www.grdstore.com/moto-oxygen-...6e0593f8b58cf1

okay great That is what I am going to do then. I tried to have him clear the code but he couldnt will evoscan do it? I will buy the TP and anti fouler plug. Thanks guys

you should be able to clear the code by disconnecting the battery for a min. or two if the code doesn't go away you may have a fried O2 sensor. hope that helps

Also you have the extension for your O2 right?
It pulls the O2 out further then the stock location.

You don't need to waste the money on a test pipe if you don't want to. You can buy a pair of spark plug anti-foulers and pull your O2 probe out of the exhaust stream to eliminate the "catalyzer inefficiency" code.

So I put this in before the rear O2 sensor and that should fix it then? Is this the same thing that I would use for the TP as well? I will be getting a TP for free from my brother but not for about a month or so.

Yes sir. Just take off the O2 sensor, using lots of WD-40 (or something similar), and tighten it into the anti-fouler plug, then tightening the assembly into your hfc/tp. Tightening specs: 33+/-3ft*lbs, or 44N*m of torque.

are there any clearance issues with these at all?

[element3927]

There shouldn't be, but you can check beforehand based on the angle of the O2 sensor's position. Just take a ruler or something to see if the additional length of the anti-fouler plug will give you a problem. If the hfc you bought was made specifically for the EVO, then you shouldn't have a problem - my tp from the Tanabe exhaust sys was made specifically for the EVO, so I didn't have any clearance issue with mine.

go on ebay and order you a cel simulator. its about 20 bucks shipped.
