Back then when im doing PI intake swap, I did spray load **** of card cleaner on TB cause I saw it was dark black stuff ( I driving import and if you clean out the TB it will help car idle and run alot better ). I dint knew those black coat is there for a reason, I clean it out completely
. My car ran and idle fine now, but its bad for the engine ? do i need new TB ? thanks
