my emissions were fine under load, but at idle the hydrocarbons were at 457(ppm), and the max is 400, the CO2 at idle was 2.35 %

when i tuned the carb, under load is still fine, and the CO2 at idle went down to .26%, however, the hydrocarbons went up to 1027(ppm) this is very perplexing to me, and i am wondering what could cause this, and if there is any "easy fix" the truck is running good, the way it is, any help would be apprecited. thanks HJ
