So whatever I did ended up greatly compromising fuel economy.....I'm talking maybe 12 to 13 mpg highway. Needle was at halfway mark when I left home with 146 miles, now it's between the R and the last bar at 182 miles. Blue smoke at idle with engine idle surging up and down between 500 and 1000 rpm
