Well i've already extended mine at the beginning of the summer and i have had a problem with a cel light that comes on after 1000-3000 mile driveing cycles. I am taking it in tommorrow since the light is on and i haven't reset it but my main question is: After you extend the o2 wires does it matter which o2 goes where. I put the first one in the 2nd spot and vice versa cause one was a bit longer. Could this be my problem.

This might belong in help...sorry if it does

Thanks

well if i would do it, i would take the first one and still make it my first one. same goes for second. it seems to me that is your problem. just like on a distributar would you put #1 on #2 and 2 on 1? nope.

 

yeah, you need to have the right ones before and after the cat... that might save you some money at the dealership

 

Yup, if you look at the sensors, you'll notice that they are different....i just put on my headers yesterday.... smile.gif
