Hey,

I was searching the board and couldn't find a DYI for fuel induction system cleaning. Dealer states i have some carbon build up at intake throttle plate. How would I take care of this, or is it better for a shop to do it?

You might also benefit from using 44K too.

Videos on YouTube showing how to clean it - just be careful if the body has a sensor in it.
If it has, just spray, don't wipe with cloth.
I cleaned the Accord's carefully, then sprayed more with the engine running - you'll need someone to prod the pedal to prevent it stalling.
Short bursts rather than prolonged ones are the way to go.

 

I swear by SeaFoam. They even have a new can with a nozel to get in the throttle body without having to aspirate though a vacumm line. Awesome stuff.

I can't say I've personally used Seafoam, but I have heard of a DIYer who hydrolocked an engine with it.

The most effective, safe induction service involves simply running the engine while you use an induction tool like the that recommended to slowly meter in the induction fluid. A few drops per second at idle. It'll take about an hour.

I recommend an induction service every 30k to guests with direct injection cars, including dual direct/port system (D4S system like the LS460)

 

 

I have used BG44K in many vehicles and it does work well. Redline as a fuel system cleaner also works well... Dealers like to charge you for a service that most of them just pour in the tank.
