I got mine from oreaily should be at any auto store… It’s an odd part so
the guy might not know what your talking about
Hi all, where did you get your spark plug non fouler? I am having trouble
finding it. Thanks.
Umm you probably have a bad exhaust manifold or catalytic converter! It
just seems like you want to cover the issue up rather then fix it.
I have change BOTH of my CATALYTIC CONVERTERS, ALL SPARK PLUGS, AND THE O2
CENSOR! I have a protege 2003, and mechs always say there is nothing wrong
with my car yet I keep getting this error OR misfire.
hey do i need to put a nonfowler on the o2 sener on the engine or just the
one after the cat?
I did this after a Obx catless header install. Worked great. Also why the
hell would you leave that ugly ram air box if you have a cold air intake??
This isnt a solution for the 2006 Mitsubishi Eclipse GT because the cats
are mounte on the manifold. THe downstream sensor is not under the car like
this one is.
just after the cat
I try this on my 2005 Hyundai tiburon but no luck .. With my full exhaust
no cat/no luck the light come back ON every 28 mileage
worked like a charm mate, thanks!
Hey, thanks for the tip. My check engine light is gone. Passed the
emissions diagnostic test. Saved me a heap of money for repairs.
