Default Throttle body and fuel injector service - is it really needed?

The dealer said the reason I'm getting a low boost (0.32kpa) is because I need Throttle Body & Fuel Injector Service. This isn't covered under warranty and costs $250. Does this sound right to anyone (price and service)? I told them not to fix it and that i would get a second opinion. THANKS

Default all they do is run some detergent through it or take the throttle body off and spray it with

carb cleaner till all the nasties are gone. This is a DIY project.

Default Look at it this way:

Buy a bottle of carb cleaner and bottle of fuel injector cleaner. Get a new throttle body gasket. All that will run you probably about $30.

Remove the throttle body and clean it out, replace the gasket, reinstall the TB. Takes you 1 1/2 hours , if you really take your time.

Add fuel injector cleaner to gas tank, fill up.

Or have the dealer do the same thing and probably screw something up. That will cost you $250 and take a few hours.

It's your call.
