i just took my '87 for emmisions friday it failed on all, but the NOX was doubled. the person that owned the 240 before had gutted the cat. The reason the NOX was doubled for me was becuase the timing was ahead 4 degrees (the person before me had done this). anyway it makes the combustion hotter. Check you timing.... Hope this helps.
