1992 SHO CA Emission failure
The car runs fantastic and since I sleeved the EGR tube with 304L it even sounds great(no whisper leaks) My problem is I have trouble thinking a minor leak in the EGR tube would cause high NO readings - everything else passed but NO reading @ 15mph measured just over at 540 vs 537 (ppm) &...- Greg Millard
