1991 Acura NSX: New Oxygen Sensor and Gaskets

November 14, 2011

Our 1991 Acura NSX was out of commission for a few days to address the check engine light and trunk leak. Well, we picked it up from MD Automotive in Westminster on Friday. That was when I tossed the keys to Kurt...

What I didn't tell Kurt was that the tail light seals were replaced. He managed to make the brand new Acura seals ($25 apiece) leak just as well as the worn seals they replaced. Way to go, Kurt. Now we know those weren't the problem.

As for the check engine light, at least it hasn't reappeared. Since we swapped out the rear oxygen sensor the car seems to be just fine. Now it's back to the drawing board for the trunk leak.
