Last year early maybe Spring or beginning Summer I had the surging idle issue...after research and trying different things I had exposed full TB and had is cleaned and wiped down with TB cleaner spray...all was fine til I reached home Sunday night and noticed it surging...I take it cleaning it worked well for a year...but it's back now so I'm thinking what are hoses that I should also check/clean that can cause ventilation issue to point the TB gets dirty thus surging occurs? I presume any hoses attached but what can be clogged that I may not know?


I can just clean out TB and wait til return or just fix it once and for all.
