Hello all,


My 84 245 failed it's test today, for the first time in the ten years that I've had it. Here are the numbers, (HC) 1.8000 GPM max. / reading 3.7687
(NOx) 2.8000 GPM max. / reading 6.4298


When I got home I looked the car over closely, and it failed the jiggle test. I discovered that the vacuum hose that runs from the flametrap to the manifold was off. It was about time for a new flametrap anyway so I put a new one in along with a new vacuum hose. It now passes the jiggle test.

All of the other tune-up related items are in good shape. My question is would the above problem cause both of those readings to be high? And do you think I'm ready for a retest?

Thanks,
