Default Clean Throttle Body

What's the best way to clean the throttle bore? Do I spray it with carb cleaner while running as you do with a carb? Thanks.

I'm working on the rough idle when warm issue and am starting with this cleaning. Next, I'll get some of that BG Products 44K.

Personally if it was me, and I had the time, I would take it off, remove the sensors, spray it down and give it a good wipe, get into all the nooks and crannies and if possible soak it in alcohol for like an hour or so.

If I'm pressed for time, I would just run it at idle and spray seafoam into the TB.

The HO throttle bodies are easier to clean if removed as the IAC is a bear to get off with it installed.

The rEnix you xcan go either way. Always use a new gasket.

Thanks. I'll take it off. I like the idea of the alcohol soak too.

These basics have improved the rough idle when warm issue. I found four grounds and cleaned them all. I disconnected and lubricated (CRC 2-26) every electrical connection under the hood. I removed the throttle body and cleaned it. Also soaked it in alcohol as suggested. Cleaned up the IAC valve too as it had a lot of soot on it. Anyhow, not much money with good results. Thanks.

What kind of alcohol do you soak it in? Regular rubbing alcohol? I am thinking I need to take mine off and clean very well and wan to make sure I clean with right chemicals

Carb cleaner, brake cleaner, lacquer thinner, Jose Cuervo. Whatever gets it clean, and they all will get it clean.

The very best carb cleaner I have found is the Carquest brand.

takes off the brown film quick.

Brake cleaner spray cans work good also, dry quick....

After cleaning it with carb cleaner I soaked it in denatured alcohol. I usually keep a gallon of it around. You can get it at Ace or any hardware store. Good luck.

I was thinking denatured. I work at Lowes and was hoping that I would be able to get the recommended chemical from work (which I can) for my discount and convenience. Thanks for the tip
