Ive been having this problem for a few months now and cant seem to find what the problem is i have a 2010 stx with around 84000 miles and it will stall out of me when im slowing down to a stop or already stopped. I replaced the spark plugs and checked the purge value. Purge value was worked good but i had to fix the spaek plugs a few times because they were miss firing mainly 2, 3 and 7
