1989 Nissan 300ZX

I AM THE OWNER OF A 1989 300ZX THAT I PURCHASED USED IN 2013. THE CAR HAS APPROXIMATELY 160,000 MILES ON IT. APPROXIMATELY 6 WEEKS AGO, I NOTICED A FUEL ODOR AND AFTER DOING SOME RESEARCH DETERMINED THERE WAS A RECALL ON THE VEHICLE IN 1996 FOR DEFECTIVE FUEL INJECTORS. THAT RECALL IS ATTACHED, I ALSO HAVE COPIES OF THE TSBS (10 DOCUMENTS TOTAL). A FEW DAYS AFTER NOTICING THE FUEL SMELL (WHICH I COULD NOT LOCATE THE SOURCE) THE CAR SUDDENLY DEVELOPED A FUEL RICH CONDITION AND THE ENGINE BEGAN TO IDLE POORLY. FOR BACKGROUND, THE CAR WAS RUNNING FINE AND AFTER LEAVING A RESTAURANT, THE ISSUE APPEARED SUDDENLY. I CONTACTED NISSAN AND THEY TELL ME THEY HAVE NO RECORD OF THE RECALL OR ANY REPAIRS TO THE VEHICLE. I TOOK IT TO MY LOCAL DEALER (DICK SMITH IN COLUMBIA SC) AND THEY TELL ME THE SAME. THEIR DIAGNOSIS IS THAT MY RACK AND PINION ARE LEAKING. I DO NOT DISAGREE WITH THEIR DIAGNOSIS, BUT I DOUBT IT IS LEAKING FUEL. BASED ON THEIR TSB, IT APPEARS THAT THE REPAIR WORK WAS NEVER PERFORMED ON THIS VEHICLE AND SINCE THE RECALL WAS ISSUED MORE THAN SEVEN YEARS AFTER THE BUILD DATE, THAT OWNER AND SUBSEQUENT OWNERS WERE LIKELY NEVER NOTIFIED OF THE ISSUE. I HAVE ASKED THEM TO PERFORM THE RECALL WORK PER THE TSB INSTRUCTIONS BUT SO FAR THEY HAVE REFUSED.
