I went and cleared the CEL and then drove ~7-8 miles to the testing place. When I got there they could tell that my engine data was just cleared and told me to come back later. So I'm going in tomorrow morning again for try 2. I got my money back which is good.

Hopefully that light doesn't come back on. I found out that if it is on for any reason they fail you.

 

marshy and fail go hand in hand

 

you'll need to set your readiness codes. from a cold start drive the vehicle at a steady 40-50mph and it should set all your codes. then bring it in asap before the check engine light comes on

 

I drove at 75 for a few minutes then 40-45 after that and it wasn't ready.
It hasn't come back on after 4 starts, 20 miles driven(About 35 minutes). I don't think it will come back on, knock on wood.

Anyone know how they do the dyno with an AWD car?

 

youll need to do it from cold start straight to 40-50mph. going straight 75 won't set any of your readiness codes.
