Car threw a code.

LeBirdNest · Jan 29, 2013

Ok Levin. Fixed my leak, still throwing 420. New o2 sensor up front an still throwing the code. I am now almost sure that its my highflow cat. Its tricking the ecu into thinking im running rich. I found multiple o2 spacers online some an inch long, some two, some angled... The farther away the better or just a tad with the smaller one? Im not positive on which one to get. Now that i think about it, i only threw this code "after" my cat swap. Which further concludes where the problem lies.

I know i thought it was there before my cat seap but i remember now that it was the code of certain death of my transmission that i rember. The 470 not 420. :doh:

Misfires on like 5 different cylinders and something with the tranny that I can't remember...

You can go to your local Napa and get one(not sure if Napa exists in the states lol).

or look for this one

I've only got one on mine and its more then enough to fix the issue. You'd probably need two if running a test pipe.

on eBay pick any of these....

Going to autozone.

Got a couple of these at autozone in the back on the wall. "18 mm sparkplug non fouler". $4.50 for both. Im gonna have to bore it out a little bit so the o2 sensor will fit up into it but once i put it on this weekend i will repost in here. Thanks for the help Levin.

1/2" drill bit is what I used. Just drill straight and not in an angle lol.

Use one

If you use both your rear o2 is never going to get a reading lol. When i tried both in my car for just a couple of mins my rear o2 was reading 0.007volts lol. Any shop that looks at that will be like "wtf". In my case i needed it to look as normal as possible.
