Dealing with the same issue. I cleaned my TB and ICV with cleaner. The idle issues persisted, then I went through 4 aftermarket ones, one of which wasn't too bad but the rest either didn't fit or wouldn't run. I finally got fed up and put the original Bosch unit in after fill/drain with rubbing alcohol then seafoam. Still having the same symptoms. Would opening it up and cleaning it do the truck, or should I get another new one?
