So where is this mysterious R16/1
I just bought a 92 300 TE 3.0L 193K mi I think it is a CA model since it has an air pump . It has some emissions issues ie: high nox 2.0659 g/km max is 1.24 g/km. HC is .0980 g/km max is .5000 g/km. Co is .1157 g/km max is 9.3200 so hi nox low everything else. Pulled the EGR hose and sucked while the engine was idiling result engine wanted to die, I believe this proves the EGR is working or at least not plugged. After some research I went looking for the R16/1 resistor to find out what it was set at but could not locate it. Next step will be to figure out how to richen the mixture up since I think it is somewhat lean. Car requires a bit of cranking to start especially when cold but it always starts. It runs well with good smooth power,. no idea about gas mileage yet, not enough miles driven yet. Cheers Dan

Should be in a harness to the inside of the brake booster.
It's a fixed resistor so there is no adjustable setting. It has nothing to do with fuel enrichment only timing as it inputs to the EZL.

Resistor
The issue of fuel enrichment and ignition timing are separate I realize but they both can have an effect on the Nox readings which is what I am trying to reduce. If I richen up the mixture or reduce the ignition timing each should lower nox. I may have to do both, I believe the EGR to be functional since when I suck on the hose with the engine at idle it want to die, Cheers Dan

When running with resistor removed I richened fuel mixture to max and gaped plugs to 40 based on recommendations in performance section. Passed emissions in GA but not sure if it would have passed north of the border.
Max would be where there is 10 point difference in average duty cycle at idle and at 2500 rpms. More than 10 points would not be in spec and less than 10 would mean leaner. This is with air cleaner in place. I will try to find the recent report and post. 3 weeks ago: Last edited by cbc atl; 12-01-2011 at 10:59 AM.

I kinda cheated
I put studded snow tires on the car to take it through the test last time. Legal in this part of the world at this time of year. They won't test it on the dyno due to Workmens Compensation regulations. Afraid a stud will fly off and kill someone. They only do the idle test which does not include nox. So it passed but I still would like to get the car running right. Cheers Dan
