You have the Volvo/Chrysler ignition used on 240s from mid '81thru 1988. It's been claimed that the V/C ICU's design can cause hi NOx, and that plugging the vacuum line to the ICU can lower NOx production with little effect on normal operation.

I first posted it on 5/21/04 (see original post here. ) At least one person has found that this solved his high NOX problem.

You can see his happy response at success story.

NOTE that he had failed with a new cat, then plugged the ICU vacuum line, put the old cat back on and passed!.
