Hello. Finally passed NJ emissions test Today. Big thanks to advice and help from Brickboard. Here is complete information which others will hopefully find to be helpful : 1987 sedan automatic 120,000 miles, Catalytic converter only 2x years old, no leaks anywhere.
Test #1 3/22/07 NOx : Standard : 1227 Reading : 2520
HC : Standard : 162 Reading : 23
CO% : Standard : 0.91 Reading : 0.01

Failed As NOx was way too high. So filled up with high octane gas instead of my usual regular and removed and plugged up vacuum hose to ignition controler.

Test #2 3/29/07 NOx Reading : 1740
HC Reading : 14
CO% Reading : 0.14

Although NOx was lower it was still too high so still failed. Removed and plugged up vacuum hose to fuel regulator.

Test #3 3/30/07 NOx Reading : 1208
HC Reading : 53
CO% Reading : 0.33

Passed !! Removing & plugging hose to ignition controler wasn't enough but in combination with removing & plugging hose to fuel regulator did the trick. With my '86 for emissions inspection about 1 1/2 years ago removing & plugging ignition control hose did the trick to the tune of over 1200 points as I recall yet this time with '87 only brought it down 780 points. Removing & plugging fuel regulator hose was good for bringing it down 532 points. Guess to sum up here maybe best thing to do is remove & plug both hoses.

Final question : Should I leave both these vacuum hoses removed and plugged up(car runs fine/same as when they were hooked up)or should I reconnect them ??

Thanks to all for your kind help with this matter.
