Hi all,

I have fitted a decat pipe to my Focus RS and wondered if anyone has had any success with this http://www.ebay.co.uk/itm/LAMBDA-02-...item1e70838b45

Basically the car already came modified from original with an Uprated Manifold, front mount intercooler, bluefin remap and K&N air filter. The only thing it was missing was a Decat which I fitted last week which turned the car into a bit of an animal. This week engine check light came on which turned out to be the rear O2 sensor. I therefore cleared the code last night, blanked off the hole where the rear O2 sensor goes and tied up the sensor still connected to the back of the engine bay thinking this would solve it. This morning after about 20 miles, the light came back on with the same code. Does the rear sensor work within a certain heat range therefore not allowing me to just tie the sensor up? Will the above sensor extender do the job?

Kind regards
David
