    2010 SLT 5.7 4x4. I'm having stalling issues and some advice I've received here suggested cleaning the throttle body. I popped off the air intake hose today and there is a large amount of build up visible. I'm considering removing the TB and cleaning it myself, but before I commit I was hoping for a guidance from you folks. Are their any parts that should be replaced if I remove the TB? And what would work best to clean it? Thx.

    Use throttle body cleaner. Taking it off would be the best way to do it. Only thing you’d need is the throttle body O-ring. They’re reusable but being 10 years old, I would replace it.

    When I did mine (2011 1500 5.7) In 2017, I just unhooked intake and connectors, unbolted the throttle body and used CRC throttle body cleaner from Canadian tire. I used a old tooth brush and be carful not to get any cleaner in around the electrical part of it. Throw everything back together. If I was doing now, I’d change the gasket.

    If you remove the throttle body disconnect the negative battery post first.Then do a throttle body relearn,which is turn the key to the "run" position with-out starting the engine,wait for the dash lights and bells to quit chiming then slowly push the gas pedal all the way to the floor and then slowly return it back to the top with-in 20 seconds,turn key off and then start the engine and drive it around the block.

    It's not absolutely necessary Lyle,but it doesn't hurt to do anytime the TB is disconnected.The truck will run with-out doing a relearn,but it is recommended you do one .You can still do it now.

    I didn’t remove mine and just slightly pushed open to clean the areas. I have got her relearned now though. Thanks @Wild one
