I going to put my camaro back on the road soon. So im going to have to get it inspected. Last time it past inspection by just by a couple of points.

The nox was high.

this time im worried it might not pass.

What are the best options to take. I heard if you run it with low gas it helps.

Also what about the emissions reducers in the bottle you add to your gas before you take the test?

any tips would be great

Thanks

 

if it is close drive it for a while befor you go, in order to get your cats nice and hot.
