On the 2.6 the fuel mix at idle using the factory setup is rich to get a smooth running engine. So while the injection does help the converter light off, it was also used to get the HC down at idle.


Is this with the carbureted fuel system or was there a fuel injection system for these? And where is the injection coming in? I thought it was directly into the converter. Do they have air injection into the exhaust manifold?

If your able to hold closed loop at idle I cant see the AIR injection doing you much good. On my Turbo motor it wont pass the sniffer if my air injection system is not working properly.

What does it fail for without A.I.R.? Is it HC? I would expect NOx to be much higher with air injection on yours.

I've been curious, did you have to go to the referee for your smog on the black truck? I'd really like to know how all that works and how it went.
