Another emissions failure
As the title states I failed my emissions test with flying colors. Here's the list of recent new parts:
Distributor
Ignition Module
Pick-up sensor
Plugs
Wires
Cap & Rotor
Oxygen sensor
Throttle Position Sensor
Y-pipe
Fuel, Air & Oil filters
The timing is spot on and I've got 20w-50 in her to keep oil pressure in her. There's no codes popping up but there is only 1 catalytic converter and I think it's original.
The HCs were through the roof (625% over average) but oddly was not a failure on my test. The fail part was the NOx and that was about 210% over average. The truck runs great around town and doesn't smoke. I had a power problem related to oil pressure but that got a lot better with the 50w oil. If I was to get a new direct fit OEM dual cat setup do you think I'll pass? Thanks for the help and other suggestions are welcome.

yes put it on, the singel cat isnt even for that truck at all sence you cant by the cats for the bronco II individually i have a hunch its it for a 2.3 ranger if its fitted on there right sence they look like it could bolt up and as you would think putting a cat desinged for a 4cly on a v6 will mosy likley not pass at all its most likley clogged as well if you do have oput it on even if your not sure it will pass cuase its prolly choking the motor as well

so waht your saying is the where cut apart and somone brought apipe up to the first one? im not sure but i think the two cats arent the same thing from the oem it may be a 2 stage process where the first cat dose one thing and the 2nd dose another and both combined make the exuast alot cleaner i say do it, there cant be much else to cuase this without burning oil

Also I was wondering if fixing the timing at like 12 degrees would be better then letting it retard it?

i friend of mine sed his fathers van fialed emmisions and all he had to do was adjust the timing i dont really know what he did with the timing but it did pass. i dont think bypassing the retard function will do anything with emissions and has a chance of making the truck run like crap why would it be retarding the spark if it made it fail emmisions? right? i hav a feeling it is the cat. i woulndt trust anything not ment to be there "n*gger rigging" often results in somthing like this happening so you should put the proper cat setup in

Update
I installed a new direct fit dual cat. I also pulled the block that locks the timing for setting it so that it wouldn't retard durring the test. Retested and passed as soon as the test started. Night and day difference!
