i bought catless headers, and love the mod. only engine light came on after a few miles (as expected) spacer came in the mail the next for the after cat o2 sensor. installed right away, and engine light goes off a few miles later. should have been end of story, but the engine light returned following day. i thought of trying another spacer with a different apurature, but instead i went with the wiring mod with the 1 uf capacitor and 1 mega ohm resistor (wired correctly) this time engine went off immediately at start of the engine. i thought i was home free again, until engine light returned again, this time with the spacer and wiring resistance in play? i guess i'll have to get a code reading to know what's going on. anyone's educated guess if i could now be overdoing the sensor mod to a too low reading or something by employing both signal reducing methods?

are you kidding? Why are you going so far out of your way to make a BS spacer work? GET A TUNE.

The code is going to read P0318: Get a fucking tune.

If you haven't seen it yet the answer is a proper tune! Its been proven that the spacer trick is dumb and temporary and you'll gain way more with a tune. Get an ecutek tune from say ft86speedfactory and get it over with
