it worked surprisingly well. I disconnected the battery for 15 minutes, then started the truck and let it run for 10 minutes with all the accessories turned off so everything could reset itself. Then I took it for a cruise and when I would come to a stop it idled much smoother. And when I took off it was smoother too. I think it was sticking in all that gunk.

Were you able to remove the throttle body completely? When I cleaned mine a few weeks ago I unbolted all four bolts but left two tubes connected because they seemed too difficult to remove and then put back on. I did not have any idle issues at the time but I was changing plugs so I decided to do the job and will again at 90K plug change. I left ,y battery disconnected for the hour and a half while I did both jobs.

One of the other members on here suggested I clean the throttle body to solve some idle issues.

So I took it apart tonight and cleaned it out. And it was Nasty.

Before - this is at 79,000 miles
79K? That was gross! What air brand of air filter were you using? K&N?

I'm sure there is some proper solvent type cleaner, but I kept it simple. I just used a micro fiber rag lightly moistened with a Simple green solution. Used a little elbow grease and it all came off. i made sure to clean out any towel debris and moisture before putting it back together.

Seemed to work just fine

I started off by just scraping off a little bit with my fingernail and the stuff was a waxy tar oil consistency

A can of throttle body cleaner and an old toothbrush works really well.

As far as TB's go though, yours really wasn't that dirty.

i'm wondering if you're a fan of the "pour" in the gas tank type of fuel line cleaners? or like, the seafoam stuff i've read about....

I use the pour in the gas tank type, but the thing is is doesn't matter as far as the dirty throttle body goes, because it is way before any fuel is injected into the system. I assume it gets dirty from the vacuum/recirculation tubes attached to the intake areas.

Dont most new vehicles have a waxy type coating on the throttlebody to help keep dirt from building up on it? Had someone tell me that a while back so i was just curious.
I personally just use throttlebody cleaner spray from Canadian Tire, but there are plenty of other sprays you can get. I just clean the throttlebody with it a lil bit, then i fire up the car and spray it into the throttlebody (making sure to keep the engine revved up because it will try to stall). Revving the engine not only keeps it running as you spray but also opens the throttlebody nicely so you can get the spray right in there to clean the intake manifold a bit while you're at it.

Be carelful with TB cleaner. It is nasty stuff. Wear gloves and glasses. I removed the TB. I sprayed it on cotton balls and q tips to do the cleaning so I did not have to worry about overspray. Then wiped off with a microfiber towel.

LOL funny you mention that. I have sprayed myself directly in the eye before and it's painful! My vision was blurry for a while afterward too. I try to be very careful ever since then.
