| Only issue was at idle. Clean as a whistle at higher rpms. I gave up and ran a methanol mix and the numbers came back about as low as u can get. Just mixed up a gallon of methyl hydrate with some non-ethanol fuel and I was good to go. I only put enough in the tank to get me to the test centre and through the test. Filled up with fresh non-ethanol fuel on my way home. I'll prob try it without the cats next time. Replacing the exhaust gaskets gets expensive.
