1991 Acura NSX: Failed Smog a Second Time

October 24, 2012

The smog station technician pointed at our 1991 Acura NSX, and then to the word FAIL on the printout in his hand. "I think you might need new catalytic converters," he advised. I was dejected. For the past 30-40 minutes I'd been running the NSX to make sure the cats were hot and ready for the test. We hoped the sensors would do the trick. Crud.

He must have seen the look in my face. The tech tried to offer reassurance, "If you bring it back in the next 30 days it is only $20 to retest." I thanked him for his time and hit the road. Back to the drawing board. And deeper into the wallet.

Smog test: $65
