Dealership...depends on what you want to replace. For example, I didn't replace my tb nor IAC gaskets when I did it. I believe it's anywhere from 50-70 for the gaskets.
50-70 for gaskets plus 6-10 cans of carb cleaner (2 dolalrs each) so just shy of about a hundred bucks. It's definitely not a 'multi-hundred dollar job.' W/o the gaskets and 6 cans of cleaner all on sale, I finished the job for about $35. Hence, it varies.
