Your TE seems to have problems with every emission test. Did you ever follow my advice to alter the spark advance map temporarily by shorting the R16/1 connector and blocking the vacuum advance.

IIRC you have an aftermarket converter, which could be an issue. They don't seem to last very long, but if you recall my test results, the above temporary mods cut my HC by nearly 50 percent and NOx by 90 percent.
