Failed emissions. Now what?
My truck has passed emissions fine the last two visits (every other year), this time it failed by a mile. Opacity max is 40%, mine registered 69%. Truck is modded per my signature, but has the DP tuner with stock setting which is what I used for the test, even ran high idle prior to taking the test. Runs fine. The only thing I was thinking doing is putting some Seafoam in the tank and running it hard on the stock setting for a while. I have a month before my tabs expire. I normally run it on the 80 HP tune.
Anyone have any suggestions? Is there a possibility it could just be a bunch of soot left in the exhaust from the 80 HP tune? Cat has been removed, but it passed the last two times without it.
